【摘要】 通过仿真研究了级联型CPS—SPWM多电平变流器在电力有源滤波器中的应用问题。在并联有源滤波器的应用系统中,由于直流侧不需要提供有功功率,级联型多电平变流器的优势得到了充分的发挥;而CPS—SPWM技术良好的谐波传输特性也得到了良好的利用。更多还原

【Abstract】 In this paper, the applications of cascade CPS-SPWM multilevel converters in active power filter are researched through simulation. In applied system of paralleled active power filter, the advantage of cascade multilevel converters is put forth sufficiently because active power is not needed on DC bus. Moreover, the excellent signal-transmitting feature of CPS-SPWM is also employed.更多还原
