[Abstract]:Active Power filter (APF) is mostly based on three-phase six-switch topology. In order to improve its reliability, a three-phase four-switch fault-tolerant APF based on component redundancy is proposed. Aiming at the fault discrimination of three-phase six-switch APF, the bridge open circuit fault is identified by using the power device withstanding voltage change, and the relationship between the APF compensation algorithm based on harmonic detection and the voltage APF compensation algorithm based on the control power supply current tracking network is studied. It is pointed out that the direct tracking compensation algorithm of power supply current is more suitable for fault-tolerant APF switching control, and the effect of midpoint offset of DC bus on the compensation performance of three-phase four-switch APF is studied on the basis of three-phase four-switch APF mathematical model. A feedforward compensation method for DC midpoint voltage difference is proposed. In the case of DC side energy storage, the active power regulation method of fault-tolerant APF is extended, and the switch strategy of APF fault-tolerant control and the current hysteresis tracking control circuit realized by hardware are designed. On the three-phase four-switch APF platform, the current hysteresis tracking control circuit is designed. The effectiveness of the proposed method is verified by experiments.
