Abstract
In this paper new 60-step inverter system for medium-to-large scale STATCOM is proposed and operating principle along with control method is detailed. A simple auxiliary circuit is employed to Improve output voltage waveform of 12-step into 60-step. The proposed scheme could be a cost effective approach in high power application such as 10Mvar to 30Mvar STATCOM. Experimental results from a 2KVA laboratory prototype show validity of the proposed method.
