摘要
功率变流器相移正弦脉宽调制（ＳＰＷＭ）技术是将变流器自然采样ＳＰＷＭ技术与多重化结构相结合，在较低的开关频率下，实现等效高频截波的效果。文章通过仿真，验证了相移ＳＰＷＭ技术在有源滤波和无功补偿系统中应用的可能性。
A novel active power filter operating with multi modular converter phase shifting SPWM technique for reactive and harmonic current compensation is proposed. Multi modular phase shifting is combination of multi converter and traditional SPWM. With this technique, equivalent switching frequency is greatly raised. The possibility of its application in active power filter is testified through simulation.
