This paper presents an analysis of steady-state and transient-state characteristics of capacitor-input-type diode rectifier with an input isolation transformer consisting of primary-delta/secondary-star windings on three-phase rectangular-voltage-fed distribution system. The validity of the analysis has been confirmed by experiments using the 2.4 kW prototype. Through the study, the usefulness of...
This paper presents a new method for achieving line loss minimization and voltage regulation in the loop distribution systems, simultaneously. First, the fine loss minimum conditions in the loop distribution systems are presented. Then, load voltage regulation by using the shunt compensation is presented. In order to achieve these two objectives, simultaneously, the unified power flow controller (UPFC)...
This paper presents diode rectifier circuits with commutation capacitors in the three-phase rectangular-waveform distribution system. The commutation capacitors can improve the input total power factor and realize the zero voltage switching of the diodes. From the analysis, the authors also propose the design method of the rectifier circuit. In order to verify the effectiveness of the proposed method,...
