Abstract

We have investigated the voltage regulation and speed control of an induction machine with multiple stator windings using a digital signal processor (DSP). Multiple functionalities are integrated in one machine: mechanical drive, as well as electrical power generation and conversion. One stator is driven with a three-phase inverter while the voltages on the other stators are rectified to provide a DC output. By using zero sequence harmonics in wye-grounded windings, the control for DC output voltage regulation can be made orthogonal to that for speed. In this paper, we study some of the challenges and solutions to speed control in tandem with closed-loop voltage regulation in this type of machine
