Proposes a three-phase four-wire APF with four-leg topology based on one-cycle control. Main circuit adopts three-phase four-leg power topology. The fourth bridge arm connects to the zero line, which can inhibit the system zero sequence current. This topology is suitable for high power balanced and unbalanced load. Applying one-cycle control strategy, compares with the traditional control method of APF, it has advantages, such as fast dynamic response, strong anti-interference ability and so on. Meanwhile, the circuit structure is simple, low cost and easy to implement. Simulation and experimental results show one-cycle control with three-phase four-leg APF can effectively compensate harmonic, zero sequence and reactive current.
