Abstract
In this paper, to achieve a compact and efficient bidirectional AC-DC converter for an electric vehicle, a single-stage topology with 6 switches is used. The topology utilizes two half-bridge circuits and a series resonant LC circuit. The topology reduces the cost and its volume by having a low number of switches. A control method utilizing the duty-cycle of two half-bridge circuits and the phase-shift between them is proposed. The control method guarantees ZVS for all the switches and optimizes the efficiency. Analysis of the circuit, design and optimal control is described. Simulation to verify the theory is carried out with PSIM.
