Abstract
A switched resonant power converter applies AC to an induction motor. The power converter controls the magnitude and phase of the motor current, and tuning the stator flux accordingly in order to control the motor speed. A preprocessor operates on a speed command signal by getting the user speed command input to produce amplitude and phase-related signals for application to inputs of the power converter control.
