ZETA CONVERTER FOR ELECTRIC VEHICLE BATTERY CHARGER

Abstract: A Zeta converter is a DC-DC converter which works as a buck-boost converter with a non-inverted output. This paper focuses on a battery charger for an electric vehicle based on zeta converter fed from a pv array. The control technique used here is perturb & observe technique to get the appropriate duty ratio of the gate pulse for the switch of zeta converter and to achieve the maximum power point from pv array. This technique is used for this mission due to its simplicity and its quick response to achieve the mpp and can be easily implemented in low cost system. In this a complete analysis of the zeta converter applied as a photo voltaic battery charger is carried out. The proposed system is simulated using MATLAB Simulink.
