In this paper, a new hybrid photovoltaic-battery powered DC-DC converter topology is proposed. The proposed topology is realized by cascading buck-boost converter with high step-up converter. High voltage conversion ratio has been achieved using hybrid switched capacitor technique. This proposed topology limits the voltage stress across the semiconductor devices to half of the output voltage. A 400W hybrid photovoltaic-battery powered system with 220V DC output is designed and simulation results have been verified using MATLAB/SIMULINK.
