Integrated multiport converters are becoming a big requirement now-a-days compared to conventional conversion topologies. In this paper, a three-port dc–dc converter combining photovoltaic (PV) and battery power for high step-up applications is proposed. The proposed converter consists of five power switches, two coupled inductors, and two active-clamp circuits. The coupled inductors are used to achieve high step-up voltage gain and to reduce the voltage stress of input side switches. Two sets of active-clamp circuits are used to recycle the energy stored in the leakage inductors and to improve the system efficiency. The proposed circuit is designed by usingMATLAB SIMULINK and the results are verified.
