Control Strategy for Resonance Mitigation and Grid Harmonic Suppression in Three-Phase Diode Rectifier-Fed PMSM Drives With Small DC-Link Capacitance
This article proposes a robust control strategy to minimize grid current harmonics in three-phase diode rectifier-fed permanent magnet synchronous motor (PMSM) drives featuring a small DC-link capacitance. First, a virtual impedance-based active damping scheme is introduced to emulate a series R-C damper. This suppress...
