A detailed analysis and experimental evaluation of a split-phase inverter mode for 1-ph/3-ph universal voltage input electric vehicle (EV) on-board charger (OBC) is introduced. The power-factor-correcting (PFC) / inverter stage in the OBC is based on a simple continuous-conduction-mode (CCM), pulse-width-modulated (PWM), boost-type active soft-switching cell. The operating region of the split-phase inverter is investigated and experimentally verified. Due to soft-switching, the inverter achieves high efficiency, peaking at 98% at full load, at 150 kHz switching frequency.
