This paper proposes a half-bridge LLC resonant converter with two resonant tanks for plug-in electric vehicle (PEV) battery charging. Each resonant tank is connected with one of the centre-tapped primary windings of the power transformer. Both resonant tanks are fed alternately by a half cycle of the switching pulse in one period. The converter is designed to operate below resonance zero-voltage switching (ZVS) region to reduce switching losses and to achieve output DC voltage range 250V-420V with 400V input DC voltage for depleted PEV battery. MATLAB Simulink is used to simulate the circuit with 1.5 kW maximum power and the simulation results show that the converter can meet the constant-current, constant-voltage (CC-CV) charging requirements of the depleted PEV battery.
