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. WebA flyback transformer inductor is a coupled inductor that can store energy and provide coupling and isolation for the flyback converter. The primary winding of the transformer is directly connected to the input voltage source storing energy in the transformer.
