This paper describes the PWM-VSI controller of three-phase UPS system using stationary reference frame This controller meets the specification the UPS inverter output voltage even under the unbalanced or nonlinear load. This controller is also constructed with duble control loop of the outer voltage control loop and the inner current control loop For the fast response of the output voltage control, yhr inner current control loop of the capacotor current os used To get the good property against overshoot, the IP controller us used. The outer voltage controller IS designed with P controller and the high gain transfer function is used for the zero steady state error. All control gains of both controller is designed base on the CDM method
