A new three-port DC-DC converter for renewable energy systems with battery storage is proposed in this paper. The proposed converter is employed to manage the energy supplied from different sources, here the photovoltaic solar arrays and the battery, and deliver a continuous power to the output loads in the best suited form. Traditionally, three different DC-DC converters should have been used for this purpose. However, the proposed converter not only retains the major desirable features of three DC-DC converters, but also reduces the cost and improves the power density of the power system. It has many advantages such as high voltage gain in low duty cycles, low inductor current ripple and conduction losses, high efficiency and also the low number of switches. Three different scenarios are simulated to corroborate the performance of the proposed converter. The simulation results show that the proposed converter has the capability to track the maximum power point (MPP) of the PV system and also control the battery charging/discharging according to the load and the PV system power.
