Abstract :
A drive comprising a high power GTO and a fast switching IGBT is considered for a large PMSM, where torque ripple is a primary concern. The IGBT is used for attenuating ripple due to the large GTO´s low switching frequency. A hierarchical, passivity-based dynamic feedback compensator guarantees global exponential stability, and a custom space vector PWM (SVM) strategy prevents stray, 0-sequence currents. The prevention of such currents between inverters is essential for the successful implementation and is addressed by the combination of the master-slave compensator structure with the matching SVM strategy.
