This study presents the full‐bridge dc–dc converter (FBDC) operated with customised pulse width modulation (cPWM) for electric vehicle (EV) battery charging. The proposed cPWM retains all the benefits of the popular conventional phase shifted modulation (PSM) with minimal modification in the pulse width while further achieving the zero voltage switching for the active switches of the converter. The cPWM gating technique results in minimal circulating loss and switch conduction loss in comparison to PSM gating technique and higher efficiency. The detailed operation of the converter is presented with analysis. The theoretical waveforms of the converter and power loss analysis are discussed. A 540 W, 80 kHz experimental prototype is developed to validate the theoretical analysis. Finally, the comparison between PSM and cPWM is presented.
