Abstract

Highly efficient high potential energy conversion is designs are necessary to the developing high potential and high energy consuming electric vehicle (EV) applications. This paper introduces the novel voltage doubler inductor with phase shift full bridge (PSFB)converter is presented. In some 800v EV Requirements, this model help to reduce propagation losses and enlarge the energy density. The suggested topology increases voltage gain without raising the transformer turns ratio by utilizing the voltage-doubler inductor. This method lessens the stress on the devices and minimizes leakage inductance. The overall conversion efficiency is also significantly increased by the phase-shift control strategy’s ability to soft-switch operation over a broad load range. The suggested converter’s steady-state performance, soft-switching characteristics, and component stress distribution are examined in this paper. Simulation and experimental results support the effectiveness of the topology, showing high efficiency, lower circulating current, and suitability for next-generation high-power EV power trains.
