摘要：

A circuit technique that reduces the boost-converter losses caused by the reverse-recovery current of the rectifier is described. The losses are reduced by inserting an inductor in the series path of the boost switch and rectifier to control the di/dt rate of the rectifier during its turn off, The energy from the inductor after the boost switch turn off is returned to the input or delivered to the output via an active snubber.
