Analysis and simulation are carried out with the four-arm inverter, the simulation results verify that the APF with one-cycle control can dynamically and effectually compensate the harmonics, reactive current and zero sequence current.

• 在对四桥臂变换器的三相四线制有源滤波器进行分析、建模的基础上,进行了仿真研究,仿真结果表明单周控制三相四线制有源滤波器能有效地补偿系统谐波、零序和无功电流,而且响应快、补偿性能好。
