Abstract :
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.
