This article proposes an adaptive power decoupling control strategy for a single-phase rectifier with an unbalanced split-capacitor decoupling circuit. Since a capacitance mismatch estimator is integrated into the control strategy, the impact of capacitance mismatch is eliminated. Meanwhile, the capacitance mismatch estimator can provide an auxiliary online monitor for the health of split capacitors. Moreover, the mechanism of capacitor voltages self-balance is explained. Finally, experiments are conducted to verify the effectiveness of the proposed method.

具有不平衡直流分离电容器电路的单相转换器的自适应功率去耦控制

本文提出了一种用于具有不平衡分离式电容器去耦电路的单相整流器的自适应功率去耦控制策略。由于电容失配估计器已集成到控制策略中，因此消除了电容失配的影响。同时，电容失配估计器可以为分体电容器的健康状况提供辅助在线监测。此外，还解释了电容器电压自平衡的机制。最后，通过实验验证了所提出方法的有效性。
