Abstract

It is shown that ETM-PWM (error tracking mode-PWM) schema has an excellent tracking characteristic even though when the condition is close to the actual distribution system by simulation results using PSCAD/EMTDC. The current control ability of ETM-PWM is also examined for the case; when there is a difference between a control period of the major loop controller and PWM pulse generation for current control, and the case of installed the multi power converters in the neighborhood. No interference occurred and the effectiveness of the ETM-PWM scheme has been proven
