Soft-switched Cuk Converter With A Single Active Switch

A New, Soft-switched Boost Converter with Isolated Active Snubber

A boost converter which employs an isolated active snubber to reduce the losses caused by the reverserecovery characteristic of the boost rectifier and the turnon discharge loss of the output capacitance of the boost switch is described. The proposed isolated active snubber consists of a coupled inductor, clamp capacitor, and ground-referenced N-type MOSFET. The performance of the proposed conv...

A Soft Switched DC-DC Boost Converter for Use in Grid Connected Inverters
