WebJan 9, 2024 · The inductor can be thought of as a current source containing kinetic energy (like an inert object). So, when discharges (step 4 in Fig. 2 below), it reverses its polarity and passes a current in the same direction (the object continues moving in the same direction). You can investigate the inductor behavior by this attractive Flash movie. WebThe 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 modes require a signal related to the output voltage.
