A Novel Scheme for the Realisation of a 3.6kW High Current Phase-Shift Full Bridge Converter with a Current Doubler and Voltage Mode Control

Present paper proposes a novel scheme to utilize Voltage Mode Control (VMC) over Peak Current Mode Control (PCMC) to achieve a wide output voltage adjustability range with a Current Doubler output circuit in order to overcome the issue of inductor current imbalance. The proposed scheme is validated in an actual prototype of a 3.6kW/30 V-120A Phase Shift Full Bridge (PSFB) converter.
