Abstract

A new double bridge parallel, voltage source converter is proposed, based on reinjection of dc voltage via the neutral point of the standard 12-pulse converter. The ideal reinjection waveform for complete elimination of harmonic content is derived and a practical approximation is proposed, which converts standard 12-pulse into a 60-pulse configuration, which meets strictest voltage and current harmonic standards without the assistance of filters or PWM.
