摘要：
The integrated three-port power converter (TPC) is widely used in renewable power system due to its characteristics of high conversion efficiency, high system integration and high power density. Traditional PI control can be used in TPC systems, but its basic characteristics make it difficult to achieve the optimal dynamic performance of the system. Therefore, a novel scheme for TPC load mutation and power distribution based on capacitance charge balance (CBC) was proposed. By calculating the optimal control time points and duty cycle series according to the theoretical ideal dynamic response curve, the optimal dynamic performance of the system was achieved. Finally, a full-bridge three-port converter (FB-TPC) prototype was designed and the effectiveness of the proposed control method was verified by experiments. © 2020 Chin. Soc. for Elec. Eng.
