Abstract

This paper proposes a battery charger for an Electric Vehicle (EV) based on Zeta converter. A Zeta converter is a fourth order DC-DC converter which works as a buck-boost converter with a non-inverted output. The Zeta converter is controlled to extract the maximum power from a Photovoltaic (PV) array to charge the EV battery. The PV array is composed of 280 watt PV modules. The Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) technique is used to obtain the maximum power from the PV array. It is also used to get the appropriate duty ratio for the Zeta converter switch. The proposed system is modeled and simulated using the EMTDC/PSCAD software. Simulation results are presented to assess the performance of the proposed system.
