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%.
