This paper describes the design and simulation of a 7.75-kW, full-bridge, bi-directional isolated dc-dc converter using a 12-kHz transformer and battery energy storage system. The full bridge scheme is widely used for the high power application. High frequency transformer is used for isolation purpose. The dc voltage at the high-voltage side is controlled from 650 to 700 V to low-voltage side battery voltage of fixed 310V. Software tool PSIM is used to obtain the simulation result of the converter. The voltage and current feedback are compared with their references.
