Abstract

This paper presents a modulation technique for flying capacitor multilevel inverter. The proposed modulation improves power quality, reducing the total harmonic distortion and combining the advantages of two modulation techniques: HE-PWM and CSV-PWM. In order to validate the proposed method, experimental results have been included concerning a three-level 6 kW, 0.92 power factor flying capacitor inverter. The experimental results presented THD around 41.38%.

基于CSV-PWM和HEPWM的飞电容多电平逆变器减THD调制技术
提出了一种飞电容多电平逆变器的调制技术。该调制方法提高了电能质量，降低了总谐波失真，并结合了HE-PWM和CSV-PWM两种调制技术的优点。为了验证所提出的方法，给出了一个3电平6kw、0.92功率因数的飞电容逆变器的实验结果。实验结果表明，THD约为41.38%。
