Overvoltages due to these sudden interruptions may be of the order of 2.5 to 3 times the normal voltage. When a circuit breaker interrupts reactive current any magnetic energy in the reactor is exchanged with electrical energy according to the relationship: 12LIc2=12CV2where L=inductance Ic=...

A quick answer is high efficiency. In an SMPS, the transistors are operated in switching mode instead of linear mode. This means that when the transistor is on and conducting current, the voltage drop across its power path is minimal. When the transistor is off and blocking high voltage, th...
an input signal applied to port A will cause a current to flow through the transformer and experience a 180° phase shift by the time it arrives at port B. Similarly, a current will also flow through the resistor, R int and will not experience a phase shift by the time ...
Tempera- ture rise (°C) equals thermal resistance (°C/Watt) times power loss (Watts). ∆T = RT × PL Ultimately, the appropriate core size for the ap- plication is the smallest core that will handle the re- quired power with losses that are acceptable in terms of transformer ...
lo Resonant State: tl -t2 The resonant portion of the conversion cycle begins at t1 when the voltage across resonant capacitor VCRequals the input voltage VIN' and the output catch diode begins conducting- At tI, current through the resonant components IcR and ILR equals the output current 10...
(kink) very quickly to ensure our current is as stable it can be. Because of this, we can't rely on the microprocessor to sense the current, calculate what the current should be, calculate what the resistance should be to get that current, convert that to a voltage the MOSFET needs to...
A third point of difference is that the output (at the collectors of Q3–Q6) is in the form of a current, and can be converted back to a voltage at some other impedance level to that used at the input, hence, can provide further gain. By combining both output currents (typically, ...
As a general rule of thumb, dt is selected such that it is 10 to 100 times smaller than the smallest time transient occurring in your simulation. For example, if the switching frequency equals 20kHz, the period equals 50μs. To have at least an accuracy of 1% in the dutycycle, time ...
During diode emulation mode, a controller controls a magnitude of current supplied by an inductor of a power converter to produce an output voltage that powers a dynamic load. In re
