This paper presents an improved structure for static synchronous compensator (STATCOM) system based on hybrid multilevel H-bridge converter. In the new structure, the chosen of dc capacitor capacitance is considered for every module, which will reduce the dc capacitor capacitance and reduce the cost of the system. A novel system control and dc capacitor voltage balance control strategy is presented...
