Synchronous rectifier type series resonant converter for operating in intermittence mode

摘要

A synchronous rectifier type SRC for operating in an intermittence mode, which includes: an input power for supplying an input DC voltage; an input-side switching unit; a transformer with a primary winding and a secondary winding; an output-side switching unit for switching; and a gate driving circuit for detecting. According to the synchronous rectifier type SRC, a no-load characteristic can be controlled with an easy scheme and a simple construction. In addition, a simple resistor is added, and thus dead time can be generated. Consequently, it is possible to simply reduce switching loss that may occur in zero voltage switching.
