Abstract
The voltage and current ratings of FACTS equipment place it at the limit of semiconductor technology. The multi-level converter is examined here to compare its performance with the 2-level multi-pulse converter in terms of the number and rating of the devices, harmonic distortion of the AC side waveforms, harmonic current flow in the DC side capacitor, capacitor ratings and overall control requirements. From this study it is concluded that a multi-pulse arrangement of multi-level converters, each with a small number of levels, can provide very large power ratings and achieve low distortion with the restriction of line frequency switching.
