摘要：In permanent magnet synchronous motor (PMSM) drive systems, inherent inverter nonlinearities cause current distortion and output voltage fluctuations, which in turn lead to increased current harmonics, aggravated torque ripple, and reduced system efficiency. To address this issue, this paper develops a more precise inverter output voltage distortion model by analyzing the instantaneous switching states of the upper and lower power devices, explicitly considering the effects of device voltage drops and parasitic capacitance. Based on this model, an online compensation method is proposed. A sync
