Abstract
The inverter technology gaining interest in high voltage high power is likely the multilevel inverter. The main characteristic of a multilevel inverter is able to reduce each power device voltage stress. Static Synchronous Compensator (StatCom) is the major application of the inverter to compensate reactive power in power system. Compared with traditional StatComs, multilevel StatComs exhibit faster dynamic response, smaller volume, lower cost, and higher ratings. A novel structure of StatCom with delta-connected multilevel inverter is proposed. The SPWM technique, which offers simplicity and good response, is used in the multilevel StatCom switching control strategy.
