摘要: In this paper, three-phase unbalanced-voltage compensators using ac choppers are proposed. The proposed made up of three single-phase and transformers for compensation output voltage regulation. use which solve the commutation problem, limit switch stress to maximum line voltage, also raise efficiency regenerative dc snubbers. Compared with previous that complex source inverters, utilize or voltages in 30° phase shift as input chopper. Then, give high efficiency, fast dynamics, simple power circuit, reduced control circuit. It is shown via some simulation experimental results presented good dynamic steady state...
