Research on Vector Control of PMSM Based on Three-Level NPC Inverter-Fed

Abstract:

The neutral point clamped (NPC) pulse width modulation (PWM) inverter has been put into practical use for large capacity AC motor drives because of its less distorted output, lower costs and better control performance. This paper suggests a way to improve the performance of permanent magnet synchronous motor (PMSM) by using the three-level NPC inverter. Firstly, the three-level NPC inverter space voltage vector pulse width modulation (SVPWM) technique is analyzed in detail. Then, the NPC inverter is applied in PMSM vector control. Finally, a simulation experiment of the proposed control algorithm is carried out. The simulation results show that the proposed method can effectively suppress the torque ripple and improve driving performance for the PMSM drive.
