Introduction and application of magnetic components

In almost all power circuits, magnetic components, inductors or transformers are indispensable. For example, the input and output terminals use an inductor to filter out the harmonics of the switching waveform; in the resonant converter, the inductor and the capacitor resonate to obtain a sine wave voltage and current; in the snubber circuit, the inductor is used to limit the power device current rate of change.
