摘要
文中提出的基于载波相移(CPS-SPWM)技术的级联型变流器同时具有CPS-SPWM技术与多电平交流技术的优点,因而有良好的工程应用前景。在并联有源电力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。
A novel cascade multi-level converter with carrier phase-shifted SPWM (CPS-SPWM) technique has been proposed in this paper. This converter is with good prospect in engineering due to its perfect performance. In applied system of paralleled active power filter, the advantage of cascade multilevel converter is put forth sufficiently because of no need for active power on DC bus. Moreover, the excellent signal-transmitting feature of CPS-SPWM is also employed all right. ....晻
