Abstract

This study describes a series resonant converter for an all-purpose EV charger that is controlled by pulse width modulation (PWM). The boost mode of a series resonant converter is the topic of this work. A series resonant converter may span a huge range of gain with a high and flat efficiency curve by adopting two PWM boost switches with a complete bridge rectifier. The suggested converter's secondary side rectifier progressively changes from a complete bridge rectifier to a voltage doubler rectifier as the output voltage rises.With complete bridge and voltage doubler rectifiers, the proposed converter automatically achieves "two peak efficiency points" since the switching frequency is locked to the resonant frequency in boost mode. The suggested converter provides a high and flat efficiency curve because two peak efficiency points restrict the efficiency decline across a broad range of gain. On a prototype with an 800 V input and 200-950 V/3.3 kW output, the efficacy of the suggested converter and control has been confirmed.
