Abstract
This research presents a open - end winding induction motor drive for harmonic mitigation using active filtering control. Two independent voltage source inverters power the open stator windings in open ended winding motor drives. When two two-level inverters are combined with half the DC link voltage, a three-level inverter is produced. Normally the two inverters share the power requirement of motor equally. In the proposed technique, a primary two-level inverter controlled by space vector pulse width modulation powers the motor from one of the open ends. The stator windings’ other end is supplied by a secondary inverter equipped with a floating capacitor. To reduce phase voltage harmonic distortions, the secondary inverter is run using a series active power filter control technique. The filter scheme’s reference voltage is determined by extracting the fundamental component of the primary inverter’s output voltage. Comparing the proposed approach to the traditional three-level inverter implemented with an open-end winding induction motor, simulation and experimental findings demonstrate a considerable reduction in phase voltage and current harmonic distortions. This enhancement is made without the need for any additional hardware.
