In this power tip, I will discuss the design of clamping circuits for synchronous rectifier MOSFETs at a high switching frequency. where Np and Ns are the transformer’s primary and secondary windings, ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer ... MOSFETs’ RDS(ON)! The circuit was compared to a popular KBU8B silicon diode rectifier.
