A general procedure for analyzing a multiphase chopper-motor system is presented. The analytical express to obtain complete solutions for load current, load voltage, and individual phase currents are developed. The validity of the analysis developed is checked for a two-phase chopper case. This analysis is claimed to be an improvement over all existing methods for predicting multiphase chopper-motor performance. Results of experimental investigation on a separately excited dc motor fed by a two-phase chopper show vividly the improvements achieved in the source current and the load current waveforms and hence in the machine operating characteristics as compared to those obtainable on the single-phase chopper. It is also shown that the torque-speed characteristics obtained with a two-phase chopper come very close to those obtained under dc mains operation.
