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
