The resonant tank coupled to the switchingcircuit receives the first AC signal and generating a second AC signal for powering a load.
谐振回路耦合至开关电路，接收第一交流信号并产生第二交流信号以给负载供电。
3
In common hard switchingcircuit, high voltage spike usually could be produced during switch transition process because of the effect of transformer leakage inductance and parasitic capacitor.
