Abstract

This paper describes a control method which combined feed back control of output voltage with the improvement on voltage utilization factor that the superposition ratio is controlled in the three-phase multilevel inverter. The purpose of this control method is to realize improvement on the controllability and absorption of the fluctuation of the DC voltage by superimposing the moderate third harmonic wave. If the instantaneous voltage ripple was absorbed, electrolytic capacitor-less will be realized.
