N2 - This paper deals with a new three-phase bridgeless interleaved (BLIL) AC-DC Zeta converter for electric vehicle (EV) on-board charger. The proposed configuration has reduced number of devices and components as compared to the conventional three-phase bridgeless (BL) Zeta converters. Further, the combination of this new configuration with the interleaving and discontinuous conduction mode (DCM) offers a compact design for on-board charger. DCM operation ensures the benefits of inherent zero current switching of switches and diodes. Moreover, the size of magnetics is significantly reduced and sensing requirement is less, as compared to CCM (Continuous Conduction Mode) operated converters. This is due to absence of PLL in the control circuit, as DCM provides natural power factor correction at input. Therefore, the size of converter is significantly reduced due to less sensing requirement, smaller magnetic components and fewer number of power devices. The proposed BLIL converter is designed and simulated in MATLAB/Simulink environment for 3.1 kW rating and to charge a 200V, 50Ah Li-ion battery. The charge time for the battery is estimated to be 3-4 hours approximately.
