Chopper Controller Based DC Voltage Control Strategy for Cascaded Multilevel STATCOM

Abstract

Abstract – The superiority of CMI (Cascaded Multilevel Inverter) is unparalleled in high power and high voltage STATCOM (Static Synchronous Compensator). However, the parameters and operating conditions of each individual power unit composing the cascaded STATCOM differ from unit to unit, causing unit voltage disequilibrium on the DC side. This phenomenon… (More)
