Abstract
A forward type voltage resonant converter with a MOSFET synchronous rectifier was investigated to reduce the forward voltage drop of rectifier diodes. A novel current snubber circuit is proposed for the MOSFET synchronous rectifier to reduce reverse recovery losses of the MOSFET´s body diode. A multioutput voltage resonant converter was investigated. A secondary current mode controller is proposed for the auxiliary output to perform precise regulation while the main output is regulated by controlling the switching frequency. Experimental results are included
