Abstract :
In this paper active snubbing is introduced to a 2-lower-switch converter. It can effectively reduce the loss caused by diode reverse recovery. Firstly its operating stages are analyzed. Then trade off of active snubber parameters are investigated. Finally it is verified by simulation study
