CONSTANT DC TO DC CONVERTER USING SEPIC TOPOLOGY FOR BATTERY CHARGING

This Paper proposes an analysis of simulation on closed loop DC-DC SEPIC (Single ended primary inductance converter) converter. SEPIC converters are considerably used converters when the input voltage gets ample variation around rated voltage. The proposed closed loop implementation of the converter maintains the constant output voltage in spite of variations in input voltage and significantly reduces the overshoot and there by improves the efficiency of the converter and provide a non-inverting voltage. The simulation of the SEPIC converter has been validate the method and shown the effectiveness of design using MATLAB/SIMULINK environment.
