提出了有源钳位准谐振变换器的一种新的驱动方式，它无需经过数字电路延时，只需一个电阻和二极管构成的小网络。

This paper proposes a new gate drive method for active clamped quasi resonant converters. Instead of a digital delay circuit, only a resistor and a diode are added to produce correct drive waveforms.

注意到，通过钳位二极管，电流峰值比带低电阻ssr更高。

Note that the peak current through clamping diodes can be rather high with low-on-resistance SSRs.
