General average model of T-type three-level converter for active compensation circuit of distribution network

The active compensation device, between the distribution network’s neutral point and the ground, compensates for the single-phase short-circuit current. And the T-type three-level circuit is a possible scheme for compensation devices. This paper proposes the T-type average model based on the above t...
