关于“双T型四电平变换器”的勘误

Chen and Wang [1] proposed a dual T-Type four-level converter with a variable-carrier voltage balancing method. The capacitor voltage imbalance mechanism was revealed in [1, Sec. III], with a conclusion that the overdischarge of the middle capacitor is the root cause of the capacitor voltage imbalance issue. This has been experimentally validated by the articles [1], [2]. Although the conclusion i...
