Abstract

A half-bridge DC/DC power converter with complementary control and self driven synchronous rectification is described in this paper. Zero voltage switching is analyzed taking into account the effect of the parasitic capacitances of the synchronous rectifiers of the secondary side. The main advantages of this power converter, which are high efficiency for low output voltage, soft-switching for primary and secondary switches and very small output filter, are shown in an actual prototype
