關于吸收二極管
反激電路MOSFET采用普通的RCD吸收,吸收二極管采用普通的1N4007和采用快恢復的FR107,其吸收尖峰的效果會有較大不同嗎?

IN4007肯定不如FR107效果好
PI say: The slower recovery time of the 1N4007GP causes a reverse current to flow back through the primary winding at the end of the clamping period. This partially discharges the leakage energy stored in clamp capacitor, C, and transfers some of the energy stored to the secondary, thus improving efficiency.
