Panel-Type STATCOM

Modular and Flexible System Design Concept

FlexVAr^® is based on Modular Multilevel Converter (MMC) technology with advanced digital control system and user-friendly HMI. Modularity is the unique feature of MMC and it uses modular H-bridge (HB) basic units with IGBT modules. Due to modular and flexible design concept, the size and output voltage of STATCOM can easily be adjusted to the customer’s needs by arranging the number of HBs in series for each phase/arm.
