FlexVAr® utilizes Modular Multilevel Converter (MMC) technology with an advanced digital control system and user-friendly HMI. The MMC structure is based on modular H-bridge (HB) submodules equipped with IGBT modules. This modular design enables flexible adjustment of the STATCOM power rating and output voltage by connecting multiple HB units in series for each phase or converter arm, providing a scalable solution for different customer requirements.
