摘要：
The paper proposes a buck/boost dc-dc converter topology based on a simple auxiliary snubber. The snubber is simple yet effective in reducing the switching losses. In addition to the conventional active switch loss reduction, the snubber can participate in suppression of output diode reverse recovery through synchronous rectifications and it can also be used to provide complete soft switching in the whole operating region through extended conduction of synchronous rectifier. Experimental efficiencies in the range of 98.5 % show that the proposed circuit is highly capable while remaining simple.
