A four-motor drive supplied from a triple three-phase voltage source inverter

Drazen Dujic

Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
