A single stage high voltage gain ZVS boost converter feasible to photovoltaic battery charger systems

In order to give support to the growing technology demand of renewable energy applications, this paper presents a new converter topology for battery charging feasible to photovoltaic systems. The proposed converter presents in a single stage a large voltage step-up, high efficiency, and reduced voltage stress on switches due to the transformer. Also ZVS soft switching is naturally achieved a lowing high frequency operation and low commutation losses. Following, it will be shown the topology, its operation principle, and the preliminary results for a 500W load.
