A Hybrid‐Frequency Modulation Method for Cascaded H‐Bridge STATCOM With the Hybrid‐Frequency Power Loop

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
To address DC‐side voltage imbalance in star‐connected cascaded H‐bridge STATCOMs under unbalanced grids, a hybrid‐frequency power loop is introduced to enable interphase power transfer. A hybrid‐frequency PWM (HFPWM) method based on voltage vector superposition is proposed, which maintains superior output characteristics for the intermediate‐frequency

HVDC Transmission with STATCOM

IOSR Journal of Engineering, 2012
Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these
