FAIRCHILD Flyback RCD电路的计算
资料介绍
This article presents some design guidelines for the RCD
snubber of flyback converters. When the MOSFET turns off,
a high-voltage spike occurs on the drain pin because of a resonance
between the leakage inductor (Llk) of the main transformer
and the output capacitor (COSS) of the MOSFET. The
excessive voltage on the drain pin may lead to an avalanche
breakdown and eventually damage the MOSFET. Therefore,
it is necessary to add an additional circuit to clamp the voltage.
