摘要

A high voltage gain non-isolated three-port DC/DC converter (TPC) is proposed in this paper. Integrated Boost-Cuk topology is modified to a TPC based on dual input converter (DIC) to serve as an interface among a photovoltaic (PV) panel port, a battery port and a load port of a standalone PV system. Principle of operation and a detailed analysis of power flow under different modes is also discussed. The output voltage relation with duty cycle of three switches under various modes of operation is also deduced. The proposed TPC has low voltage stress across the switches. The control algorithm for simultaneously obtaining maximum power point tracking and output voltage regulation is also presented. Simulation is carried out in PSIM with parameters of Kyocera KD215GX 215-W PV panel to validate the control algorithm and high voltage conversion ratio.
