Abstract：In this paper, a non-isolated three-port converter with high-voltage gain is proposed. The converter can connect photovoltaic panel, battery and load simultaneously, and the voltage regulation and power flowing between any two ports can be achieved. The power imbalance between the photovoltaic panel and battery is eliminated by controlling the charging-discharging of the battery, and a continuous and stable power supply is realizable. A high voltage gain is achieved by bringing in the switch-capacitor circuit. Finally,theoperating principle and steady-state analysisare presented in the paper. The experimental results verify the correctness of the analysis and feasibility of the converter.
