The black box model of power converter also called behavior model, is a method of system identification to represent the characteristics of power converter, that is regarded as a black box. There are two types of black box model of power converter - when the model includes the load, it is called terminated model, otherwise un-terminated model. The type of black box model of power converter is chosen based on the goal of modeling. This black box model of power converter could be a tool for filter design of a system integrated with power converters.

To successfully implement a black box model of a power converter, the equivalent circuit of the converter is assumed a-priori, with the assumption that this equivalent circuit remains constant under different operating conditions. The equivalent circuit of the black box model is built by measuring the stimulus/response of the power converter. Different modeling methods of power converter could be applied in different circumstances. The white box model of power converters is suitable when all the inner components are known, which can be quite difficult due to the complex nature of the power converter.

There are many methods used to determine passive elements. The conventional method is to switch off the power converter and measure the impedance with an impedance analyzer, or measure the scattering parameters by a vector network analyzer and compute the impedance afterwards. These conventional methods assume that the impedances of power converter is the same in the operating condition and switched-off condition. Many state-of-art methods are investigated to measure the impedance when the power converter is in operating condition.

Since the power converter consists of power semiconductor device switches, it is a nonlinear and time-variant system. One assumption of black box model of a power converter is that the system is regarded as linear system when the filter is designed properly to avoid saturation and nonlinear effects. Another strong assumption related to the modeling procedure is that the equivalent circuit model is invariant under different operating conditions. Since in the modeling procedures circuit components are determined under different operating conditions.

Eddy current losses can be reduced by making the core out of thin laminations which have an insulating coating, or alternatively, making the core of a magnetic material with high electrical resistance, like ferrite. Most magnetic cores intended for power converter application use ferrite cores for this reason.
|
|
The passive components containing resistors, capacitors and inductors can be expressed as combination of several impedances or admittances. Another expression method is to regard the passive components of the power converter as a two-port network and use a Y-matrix or Z-matrix to describe the characteristics of passive components.

Boost, Buck-Boost, Ćuk. The input is left side, the output with load is right side. The switch is typically a MOSFET, IGBT, or BJT transistor. A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load).

PWM rectifier is an AC to DC power converter, that is implemented using forced commutated power electronic semiconductor switches. Conventional PWM converters are used for wind turbines that have a permanent-magnet alternator. Today, insulated gate bipolar transistors are typical switching devices. In contrast to diode bridge rectifiers, PWM rectifiers achieve bidirectional power flow.

The flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control (in the majority of cases current mode control needs to be dominant for stability during operation). Both require a signal related to the output voltage. There are three common ways to generate this voltage.

Another important advantage of gerkotrones is the possibility of their installation directly on HV buses, which minimizes the dimensions of a protection system (unlike the aforementioned opto-electronic interfaces that require lengthy optical fibers). These advantages command gerkotrones' widespread use in commercial and military applications in on-board, mobile and stationary powerful radio- electronic equipment, in relay protection and automation systems of electrical networks, in electrophysical installations, in power converter technology, etc.

An adjustable-speed drive (ASD) or variable-speed drive (VSD) is an interconnected combination of equipment that provides a means of driving and adjusting the operating speed of a mechanical load. An electrical adjustable-speed drive consists of an electric motor and a speed controller or power converter plus auxiliary devices and equipment. In common usage, the term "drive" is often applied to just the controller. Most modern ASDs and VSDs can also implement soft motor starting.

Thermophotovoltaics (TPVs) are a class of power generating systems that convert thermal energy into electrical energy. They consist of, at a minimum, an emitter and a photovoltaic power converter. Most TPV systems include additional components such as concentrators, filters and reflectors. The basic principle is similar to that of traditional photovoltaics (PV) where a p-n junction is used to absorb optical energy, generate and separate electron/hole pairs, and in doing so convert that energy into electricity.

Payloads in the HRF-1 can operate independently regardless of their cooling and power needs and flight schedule. The HRF power converter delivers 120 V of direct current (DC) power from the utility outlet panel to the rack and converts it to 28 V DC for distribution to the payloads. Payload computer and video operations can be conducted from the ground or on the space station. The crew performs periodic checks of all connections and hardware and performs payload operations as needed.

During planned orbiter upgrades that took place subsequent to this mission, Discovery's Assembly Power Converter Units (APCUs) were removed and replaced with the shuttle-side components of the Station-Shuttle Power Transfer System (SSPTS). The APCUs converted 28VDC orbiter main bus power to 124VDC, compatible with the ISS's 120VDC main bus power. During initial station assembly missions, orbiter APCU power was used to augment the power available from the Russian service segment. With the operation of permanent main electrical systems (e.g.

The Hull magnetron was tested as an amplifier in radio receivers and also as a low-frequency oscillator. It was reported in 1925 that a magnetron made at GERL could generate a power of 15 kW at a frequency of 20 kHz. At the time Hull anticipated that the magnetron would find greater use as a power converter than in communication applications. Hull's split-anode magnetron didn't prove to be capable of high frequency or high power output and was little used.

A contracted study was continued for the implementation of superconductors on the SSP. Initial studies showed that transmission voltages could be reduced to less than 300 Volts, mitigating arcing effects. Superconductor complications included cryogenic cooling systems with armor to protect against micrometeoroid impact and specialized connectors at segment, switch and power converter interfaces. It was shown that the tremendous magnetic repulsion force (on the order of 3.5 MT/meter radially at 1 Megamp) could be used for deployment and to present an extremely rigid structure.

This method is based on the two assumptions mentioned in section Assumption, so the system is regarded as linear time-invariant system. Based on these assumptions, the equivalent circuit could be derived from several equations of different operating conditions. The equivalent circuit model is defined containing three impedances and two current sources, where five unknown parameters needs to be determined. Three sets of different operating conditions are built up by changing external impedance and the corresponding currents and voltages at the terminals of the power converter are measured or simulated as known parameters.

One method is to put two clamp-on current probes in the system, in which one is called receiving probe and another is injecting probe. The output of two probes are connected on a vector network analyzer, the impedance of power converter is measured after some calibration procedures in CM and DM measurement setups. This method is restricted with its delicate calibration procedure. Another state-of-art method is to utilize a transformer and an impedance analyzer in two different setups in order to measure CM and DM impedance separately.

The JSDF discovers that SpaceGodzilla is using Fukuoka Tower as a power converter, using it to transform the Earth's core into an energy that SpaceGodzilla can absorb, slowly killing the planet. While Godzilla wrestles with SpaceGodzilla, M.O.G.E.R.A. splits into two different mechas: the Star Falcon, a flying battleship, and the Land M.O.G.U.E.R.A., a tank with a large drill in front of it. The mechas damage the crystal fortress while Godzilla pushes over Fukuoka Tower, cutting off SpaceGodzilla's energy supply. M.O.G.U.E.R.A. quickly reforms and blasts off SpaceGodzilla's crystal-like shoulder formations, weakening him.

Fig 1: Schematic of the split-pi converter topology In electronics, a split-pi topology is a pattern of component interconnections used in a kind of power converter that can theoretically produce an arbitrary output voltage, either higher or lower than the input voltage. In practice the upper voltage output is limited to the voltage rating of components used. It is essentially a boost (step-up) converter followed by a buck (step-down) converter. The topology and use of MOSFETs make it inherently bi-directional which lends itself to applications requiring regenerative braking.

As already mentioned, the voltage generated by a variable speed wind turbine is non-grid compliant. In order to supply the transmission network with power from these turbines, the signal must be passed through a power converter, which ensures that the frequency of the voltage of the electricity being generated by the wind turbine is the frequency of the transmission system when it is transferred onto the transmission system. Power converters first convert the signal to DC, and then convert the DC signal to an AC signal. Techniques used include pulse width modulation.

Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays The inductance of the magnet is 14 Η and the nominal current for 4 T is 19,500 A, giving a total stored energy of 2.66 GJ, equivalent to about half-a-tonne of TNT. There are dump circuits to safely dissipate this energy should the magnet quench. The circuit resistance (essentially just the cables from the power converter to the cryostat) has a value of 0.1 mΩ which leads to a circuit time constant of nearly 39 hours.

Silicon carbide technologies leading to power devices continued to be pursued. This leveraged work previously funded to develop defect free and thick SiC epitaxial substrates. Although substrates could currently be manufactured with acceptably small numbers of micropipe defects, the next goal was to reduce other defects that can harm the performance of power devices. An objective was to demonstrate the high temperature operation of high-voltage SiC diodes, MOSFETs, and JFETs in a DC-DC power converter and develop models for predicting the influence of defects on device performance.

A Video Expansion port provided rudimentary signals for add-on adapters but, alone, could not directly generate a video signal (Apple produced an LCD and an RF-modulator for this port; the latter shipped with early IIcs). A port connector tied into an internal 12 V power converter for attaching batteries; this is where the infamous external power supply (dubbed “brick on a leash” by users) that was included plugged in. The same composite video port found on earlier Apple II models remained present; however, gone were the cassette ports and internal DIP-16 game port.

Energy up to 150 kW can be absorbed or released per flywheel. Through combinations of several such flywheel accumulators, which are individually housed in buried underground vacuum tanks, a total power of up to several tens of MW can be achieved. The electrical connections power low voltage motors via a DC intermediate circuit and the power converter systems are comparable to those found in plants used in the high-voltage direct current transmissions application. Power Electronics, Darstellung der Leistungselektronik, Betreiberseite beaconpower Sometimes battery storage power stations are built with flywheel storage power systems in order to conserve battery power.

Simple LED circuit with resistor for current limiting The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can cause a large change in current. Current through the LED must be regulated by an external circuit such as a constant current source to prevent damage. Since most common power supplies are (nearly) constant-voltage sources, LED fixtures must include a power converter, or at least a current-limiting resistor. In some applications, the internal resistance of small batteries is sufficient to keep current within the LED rating.

In electrical engineering, power engineering, and the electric power industry, power conversion is converting electric energy from one form to another such as converting between AC and DC; or changing the voltage or frequency; or some combination of these. A power converter is an electrical or electro-mechanical device for converting electrical energy. This could be as simple as a transformer to change the voltage of AC power, but also includes far more complex systems. The term can also refer to a class of electrical machinery that is used to convert one frequency of alternating current into another frequency.

The Station-to-Shuttle Power Transfer System (SSPTS; pronounced spits) allowed a docked Space Shuttle to make use of power provided by the International Space Station's solar arrays. Use of this system reduced usage of a shuttle's on-board power-generating fuel cells, allowing it to stay docked to the space station for an additional four days. SSPTS was a shuttle upgrade that replaced the Assembly Power Converter Unit (APCU) with a new device called the Power Transfer Unit (PTU). The APCU had the capacity to convert shuttle 28 VDC main bus power to 124 VDC compatible with ISS's 120 VDC power system.

Stirling engine development began at NASA Glenn Research Center (then NASA Lewis) in the early 1970s. The Space Demonstrator Engine (SPDE) was the earliest 12.5 kWe per cylinder engine that was designed, built and tested. A later engine of this size, the Component Test Power Converter (CTPC), used a "Starfish" heat-pipe heater head, instead of the pumped-loop used by the SPDE. In the 1992-93 time period, this work was stopped due to the termination of the related SP-100 nuclear power system work and NASA's new emphasis on "better, faster, cheaper" systems and missions.

Instructions were sometimes in Spanish or Chinese, making it difficult to use the product. Some products were shipped with plugs and internal wiring meant for the U.S. market, making them unusable in Britain (in a few cases, the company did provide a power converter, the FTC conceded). Even products usable in Britain turned out not to have been manufactured for sale there, or in the European Union (EU) generally, meaning they were not covered by manufacturers' warranties. Those who attempted to return products met with similar resistance from the website owner, Balls of Kryptonite LLC, which Karnani formed and merged the other two companies into in mid-2007.

The lithium economy is a concept analogous to other element-based economies, such as the hydrogen economy, methanol economy, ethanol economy, electron economy, vegetable oil economy, or liquid nitrogen economy but where the energy storage medium is lithium. Analogous "economies" are the "aluminium economy" where the energy storage medium (fuel) is aluminium (typically aluminium-gallium). The hydrogen economy as a low-carbon solution to land transport has problems in generation, distribution (infrastructure), on-board storage and cost of power converter (fuel cell). The lithium economy has analogous problems in all four areas, but considered separately, the routes to their solution have different absolute limits and different timescales for their solutions.

The basic principle of dynamic voltage restoration is to inject a voltage of the magnitude and frequency necessary to restore the load side voltage to the desired amplitude and waveform, even when the source voltage is unbalanced or distorted. Generally, devices for dynamic voltage restoration employ gate turn off thyristors, (GTO) solid state power electronic switches in a pulse-width modulated (PWM) inverter structure. The DVR can generate or absorb independently controllable real and reactive power at the load side. In other words, the DVR is a solid state DC to AC switching power converter that injects a set of three-phase AC output voltages in series and synchronicity with the distribution and transmission line voltages.

Meriden, Kansas, tornado as observed by the Topeka Weather Bureau WSR-3 radar. The WSR-1 to 4 series, the first operational weather radar in the United States, used the AN/APS-2F electronics, including a superheterodyne receiver, but with a larger antenna. As time progressed and experience with the original design increased, the Weather Bureau felt confident enough to upgrade the WSR-1 to WSR-1A, eventually finalizing on the WSR-3 and WSR-4 model. The WSR-4 upgrades included the removal of the original aircraft-oriented antenna in favor of a larger antenna, and the addition of a power converter such that it would now have the ability to function on conventional power.

The Doctor tells the Rills of the true life remaining in the planet and promises to help them escape, since the solar energy converters on the Rill craft have not gathered enough power to effect a lift-off. The Doctor and Vicki return to the Drahvin ship to find Steven unconscious after Maaga has tried to kill him by leaving him in a depressurised airlock. They all return to the Rill vessel, where the Doctor successfully develops a power converter linked to the TARDIS, which charges the Rill craft. Maaga leads the Drahvins in a final assault but the Chumbleys defend their ship long enough for it to power up and leave the planet.

A careful failure analysis revealed that, among plausible causes for an abrupt bidirectional loss of communication, the Solid State Power Converter (SSPC) for the transponder had, among its features, an "instant trip" shutdown in response to a high-current () short circuit. Critically, such a shutdown was not reported in the power supply's telemetry output and this lack was not documented. The non-reporting was by design, as in non-spacecraft applications it would be dangerous to automatically restore power in such an event, while in a spacecraft failure to receive means loss of mission so there is nothing more to lose by trying. Because it was undocumented the spacecraft's hardware and software had no provision for attempting to reset the SSPC if it reported good status.

A common use of the voltage converter is for a device that allows appliances made for the mains voltage of one geographical region to operate in an area with different voltage. Such a device may be called a voltage converter, power converter, travel adapter, etc. Most single phase alternating-current electrical outlets in the world supply power at 210–240 V or at 100–120 V. A transformer or auto transformer can be used; (auto)transformers are inherently reversible, so the same transformer can be used to step the voltage up, or step it down by the same ratio. Lighter and smaller devices can be made using electronic circuitry; reducing the voltage electronically is simpler and cheaper than increasing it.

European IIcs). In order to access the local character set, the “Keyboard” switch above the keyboard was depressed, which would instantly switch text video from the US character set to the local set. The DVORAK keyboard layout was not available on international IIcs--the feature had been intended to switch between international keyboards; the DVORAK layout was merely added to give the switch a function on US IIcs. In some countries these localized IIcs also supported 50 Hz PAL video and the different 220/240-volt power of that region by means of a different external power supply — this was a very simple change, since the IIc had an internal 12-volt power converter. The international versions replaced any English legends printed on the case (specifically the “keyboard” toggle switch, “Power” and “Disk Use” drive-activity labels) with graphical icons that could be universally understood.

The first step to design a predictive controller is to derive a detailed direct dynamic model (including non-linearities) of the switching power converter. This model must contain enough detail of the converter dynamics to allow, from initial conditions, a forecast in real time and with negligible error, of the future behavior of the converter. Sliding mode control of switching power converters chooses a vector to reach sliding mode as fast as possible (high switching frequency). It would be better to choose a vector to ensure zero error at the end of the sampling period Δt. To find such a vector, a previous calculation can be made (prediction); The converter has a finite number of vectors (states) and is usually non-linear: one way is to try all vectors to find the one that minimizes the control errors, prior to the application of that vector to the converter.
