Abstract
The proposed multilevel voltage-sourced converter is based on the reinjection of DC voltage pulses at six times the fundamental frequency. The extra (reinjection) components required are justified by a substantial reduction in the capacitor size. It is shown that the resulting voltage and current harmonics are well within the present standards without the assistance of pulse-width modulation. Theoretical waveforms are verified by computer simulation using the PSCAD/EMTDC package
