3상 다이오드 정류기에서 전원전압불평형으로 인한 전원전류불평형 해석

This paper investigates the effects of different unbalanced voltages with the same voltage unbalance factor(VUF) on the performance of a three-phase diode rectifier with smoothing DC capacitor. Then DC capacitor rating is determined by current turn-on mode, that is, three-phase turn-on mode or two-phase trn mode. Finally the rating of series inductor is determined by total current unbalance factor(TIUF) and be shown current wave shaping improvement of PF, THD, CF and propose guide line
