摘要
According to the power coupling problem of three-port converters, a three-port DC/DC converter based on resonating decoupling of output-side was proposed. The resonant cell is constructed at the full-bridge of the output-side to remove the power coupling effect of control quantity on photovoltaic port and energy storage port. The three-port converter is equivalent to two output parallel two-port converters, and directly uses two-port converters system control strategy, which makes the control process easier and faster and reduces the design difficulty of the control links of the three-port converter. First, the topology of the converter is introduced, and the power characteristic models before and after decoupling are established, the control stability of the converter is analyzed. An experimental prototype with output power of 500 W was built to verify the effectiveness of the topology structure and control strategy. © 2022, Solar Energy Periodical Office Co., Ltd.
