Single-Phase to Three-Phase DC-Link Three-Leg Converter with Minimization of the Capacitor Currents

This article proposes a control technique to reduce the ac fundamental capacitor current of the single-phase to three-phase hase dc-link three-leg converter. In that technique the converter load voltages are synchronized to the grid voltage. The technique can be used in applications where the load frequency is equal to the input frequency. Experimental and simulated results are presented.
