Analysis of a field oriented controlled five-phase motor drive with active front end converter

The paper presents field oriented control of a five-phase induction motor drive system. The five-phase induction motor is supplied from a current controlled five-phase voltage source inverter and the inverter is supplied from a three-phase active front end converter. The novelty of the paper lies in the development of the five-phase drive with the active front converter. The front end converter has two control loops, the dc link voltage control and the source side current control with unity power factor operation. Simple hysteresis controllers are used to control the input from the source and output to the load currents (five-phase induction motor stator current). The validity of the control is validated using analytical, simulation and experimental approaches.
