Abstract
This article addresses the underexplored field of self-sensing rotor position estimation control methods in current-source inverter (CSI) drives, an increasingly appealing topology due to advancements in monolithic wide bandgap four-quadrant switches. While numerous techniques have been devised for voltage source inverters, the pulsating vector excitation saliency-based method (PVE) emerges as a standout performer in motors with low saliency ratios, such as surface permanent magnet machines. This article guides the adaptation of the PVE method for CSI-based motor drives, emphasizing crucial aspects like addressing resonances, handling potentially unbalanced output filter capacitors, and utilizing even harmonics for permanent magnet flux polarity identification during the method's startup. Additionally, the study delves into a discussion on the benefits and challenges inherent in utilizing CSIs for motor drives, substantiated by experimental results validating the presented analyses.
