This paper presents a phase shift H-bridge DC–DC converter for electrical vehicle battery charger application. There are many conventional DC–DC converter topologies. Those are buck converter, boost converter, buck-boost, and Cuk converter. The main drawbacks of this converter are single input and single output, and these converters are not suitable for converting high DC supply to low DC supply. This paper presented a phase shift H-bridge DC–DC converter, and this converter is mainly used in step-down high DC voltage to low DC voltage, and it also provides isolation between input and output. The major applications are server power supply, telecom rectifier, battery charging system, and renewable energy system. The presented topology operated in mainly two modes of operation one is discontinuous conduction mode (DCM) and the second one is continuous conduction mode (CCM). When the battery is charged fully the mode circuit is operated in DCM mode. When the charging across the SOC is very low the circuit will operate in CCM. The simulation results are verified in CCM mode. The closed-loop PI controller is used for controlling battery voltage, current, and SOC.
