Abstract :
Conventional control strategies of three phase converter are reviewed first in the paper. Then an optimal current control method mixed with PI without small signal linearation. The controller has strongly robustness to load disturbance and system parameter disturbance. At the same time system has high-power factor. The feasibility and advantage of the control scheme is verified by simulation and experimental results.
