摘要： The present invention relates to a differentiated control method of the cascaded active power filter, wherein the cascaded links are divided into low frequency links and high frequency links; wherein low frequency links are used to generate the fundamental voltage generated by the cascaded multilevel converter; wherein high frequency links are used to produce different, separate voltage from the aforementioned fundamental voltage generated by the cascaded multilevel converter; wherein according to the given cycle, some links are selected circularly from cascaded links as the high frequency links; wherein in the control cycle, each phase links with the maximum and minimum DC capacitor voltage, as well as those links that the pulse width modulation (PWM) combination discharge and charge most to DC capacitor are found out.
