Abstract

Resonant converters with capacitive output filters are quite popular for their higher voltage gain and compact designs. But majority of these converters underutilize the transformer as they are subjected to discontinuous currents. This discontinuous currents possess huge current ripples which produce huge core losses and aggravates the temperature raise of the transformer. This paper presents a LCC-T resonant DC/DC converter with capacitive output filter operating all switches in ZCS switching mode and whose transformer current is a continuous with minimum stress on resonant tank components. This is achieved by bringing transformer in series to inductor. This theory is supported with simulation results.
