Summary A new three input converter is presented for sustainable energy applications. Two unidirectional ports of the converter are used to connect power supplies which can be controlled independently via the duty cycles of switches. For connecting storage element, one of the ports is bidirectional. Using duty ratios of the switches, battery charging/discharging can be also controlled. Since the inductors are connected to the inputs, the input current ripples are low. Higher voltage gain and other advantages of the converter such as no limitation for switching modulation and wide control range of input powers make the proposed converter suitable for sustainable energy applications. Even if one of the power supplies fails to provide energy, the converter can provide energy to the load and charge/discharge the battery without voltage gain deduction. The steady‐state analysis of the converter is discussed, and experimental results are provided to validate the feasibility of the proposed converter.
