Practical evaluation of rectangular-voltage-fed distribution system loaded by choke-input type three-phase diode rectifier through delta/star winding isolation transformer

This paper shows practical evaluation of the rectangular-voltage-fed three-phase distribution system loaded by a choke-input type three-phase diode rectifier through a delta/star winding isolation transformer. Based on experimental date obtained from a 4 [kW] setup, it is shown that the proposed rectangular-voltage-fed three-phase distribution system offers almost unity Total-Power-Factor under the rectifier load condition.
