DC-link voltage balancing method is the key technique of cascaded static synchronous compensator (STATCOM) while safety and reliability is required previously. However, independent control scheme is necessary for each H-bridge in consideration of the voltage balancing strategy, which is different from the assumption of carrier phase shift modulation algorithm. The influence of voltage balancing strategy on cascaded STATCOM was analyzed in detail and several feasible solutions were proposed, experiment results were shown to validate the presented analysis in the end. |
