© 2015 IEEE. This paper proposes a design of a single-switch non-isolated three-port converter for a standalone photovoltaic (PV) power system with energy storage. The three-port converter is obtained by combining the switches of two conventional cascaded DC-DC converters. Pulse-width modulation (PWM) and pulse-frequency modulation (PFM) are utilized to regulate the two converters respectively. The proposed design reduces the components and the size of the converter and maximizes the number of control variables. Then, the topology of the proposed converter is analyzed with its operation modes. Finally, simulation and experimental results are given to verify the proposed design.
