dc.description.abstractIn this paper, a two-stage electric vehicle (EV) architecture of an AC-DC converter is proposed for charging two batteries at a time. It consists of a three-phase multilevel boost PFC converter followed by a bidirectional dual-output DC-DC converter. Also, the DC-DC converter has a Zero voltage switching (ZVS) and isolated outputs. The two stages function independently, allowing the AC-DC stage to operate in continuous conduction mode (CCM) without affecting the duty cycle variation of the DC-DC stage. A suitable control technique is also proposed to improve total harmonic distortion (THD) and power factor, equal power sharing of two batteries. A detailed operating analysis of the proposed dual battery charger is discussed. The effectiveness of the proposed charger is validated by extensive test of laboratory prototype. © 1972-2012 IEEE.
