Design Development and Power Extension of Phase Shift Full Bridge Converter with Zero Voltage Switching

Aiming to Contribute to mission Net-Zero Carbon emission, Electric Vehicle (EV) with efficient converter design and the emerging control strategy is the utmost need for the researcher and technologists. Phase-Shift Full-Bridge (PSFB) converter is one of the efficient converters used for EV battery charging and auxiliary power supply application. Considering the power pertinence in energy storage system and auxiliary power supply, the control of PSFB is the key concern. To enhance the converter’s performance Zero Voltage Switching (ZVS) has been incorporated. This will also contribute to the cost effective, and power dense converterdesign compared to the conventional converters used for battery charging and auxiliary power supply. In this study, the comprehensive design of a PSFB converter with a MOSFET (PMTX04SE) switch for auxiliary power supply applications in EVs has been simulated using the ZVS control approach. The details analysis and the simulation results in LTspice has been presented.
