Abstract

In this study, a novel interleaved CLL resonant converter with a full bridge rectifier is analyzed. Series connected transformers in the secondary side provide to share the power in each port and reduce the voltage stresses on the switches compared to the parallel connected transformers. The presented converter topology is explored for wide input and output voltage variation without frequency changes. The topology utilizes the phase shifted PWM signal in order to regulate the output voltage under different load conditions. Energy transfer between two different DC sources and the output load is investigated. The converter works at 40, 80, or 120 V and creates an output of 0-180 V with 94.3% efficiency at 1 kW. The experimental results show that the new interleaved CLL resonant converter is an appropriate topology for EV battery chargers which is supplied by different type of energy sources such as photovoltaic, fuel-cell, wind, etc. at various power capacities.
