This paper proposes a simple phase-shifted DC-DC converter for On-board battery chargers (OBC) with reduced circulating current. Two-stage battery chargers, are typically employed with a zero voltage switching phase shifted DC-DC converter in its layout. It contains a severe duty cycle loss, large circulating current region and limited range of soft switching with changes in load. To enhance its operation, a simple auxiliary circuit with a clamped capacitor and a resonant inductor is added in the secondary side of the converter. The various operation modes involved in the converter operation is detailed in the paper. Moreover, the proposed converter reduces the voltage and current stresses on the switches. This converter is applied with the power factor correction stage to attain battery charger with wide output voltages. The design of the converter is also detailed in this paper. The simulation results with a laboratory prototype of 1 kW has been presented in the paper.
