摘要:
本文介绍了载波相移脉宽调制适用于大功率场合的理论依据,讨论了级联H桥多电平变流器较其他形式变流器的优势,采取了载波相移脉宽调制在级联H桥变流器的实现方法,采用基于CPS-SPWM调制级联型多电平变流器的并联电力有源滤波器的拓扑结构,探讨了三相瞬时无功功率理论在检测层面的应用,并对其进行仿真和分析。仿真结果表明,在较低的开关频率下,基于CPS-SPWM调制级联H桥并联型APF可以对负载谐波和无功功率进行准确、有效的补偿。

Abstract: The theory basis that fits for large capacity power electronic equipment of CPS-SPWM is introduced. The advantages over other modulation strategies of CPS-SPWM are discussed. The implementation method of carrier phase-shift pulse-width modulation in the cascade H-bridge converter is adopted. The topology based on shunt active power filter of CPS-SPWM modulation cascade multi-level converter is used. The three-phase instantaneous reactive power theory in the detection level is discussed and its simulation and analysis is presented. The results of simulation and experiment indicate that the shunt active power filter with CPS-SPWM based cascade H-bridge multilevel converters can compensate load harmonics and passive power precisely and efficiently at lower switch frequency.
