Summary

INTRODUCTION

The vehicle, an incredible invention, has always been shaping and impacting the civilization of Mankind and has been driving the progress of human society for centuries[1]. In the recent century, the use of conventional vehicles has increased to the extent that it has caused environmental and human life hazards[4]. This is because these cars burn gasoline, diesel or natural gas, producing carbon dioxide (CO2), carbon dioxide (SO2) and oxides of nitrogen as harmful exhaust components[5]. Its rated output voltage and rated output current are 80 V and 200 A, respectively, while its switching frequency range is 100-250 kHz and its resonance frequency is 153 kHz. The proposed LLC converter is employed as a DC/DC converter for a digitally off-board charger and forms a two-stage converter with an additional power factor correction (PFC) module
