| 摘 要： | 提出一种新型的面积等效多电平控制算法,并应用到级联五电平和七电平变换器中,使输出波形最大程度等效于正弦波,并具有较小的总谐波畸变率.通过数学分析和实验仿真结果可以看出.该控制技术是可行的,与指定消谐波(SHEPWM)策略比较的结果证明了该控制技术是行之有效的,并可以用于其他级联多电平变换器中.

| Abstract: | This paper presents a novel equalarea control algorithm to be applied to multilevel voltage-source inverter. The proposed method used in 5-level and 7-level inverter can generate output-stepped waveforms with equalarea sinusoidal and minimized total harmonic distortion (THD) of the output voltage or current. By using mathematic analyses and comparing with selected harmonic elimination PWM (SHEPWM), simulation waveforms and corresponding spectrums demonstrate that the proposed method is more effective for the reduction of total harmonic distortion. It can be applies to other multilevel inverter. |
