Abstract

In this paper, a topology is proposed to integrate multi-PV modules and batteries with single resonant converter used to integrate PV sources with utility grids. The topology is proposed to reduce the cost of the converters while achieving maximum power point tracking for the individual modules. The structure provides high degree of flexibility as batteries can easily be interchanged with PV modules in the system without any need for hardware modifications. Three switches are needed per PV module and the highest stress over the switches does not exceed twice the voltage of a PV module. When batteries are integrated, they could operate in charging, discharging and bypassing modes through proper setting of the switches. The switches are turned ON under zero-voltage switching throughout the system operation to minimize the switching losses. The effectiveness of the proposed structure and the validity of its performance are verified through simulation studies.
