Abstract
In this paper, a new model for a PMSM (permanent magnet synchronous motor) driver is proposed. The proposed model is envisioned as a better modulating drive current waveform. In the proposed system the modulating drive motor current waveform is more similar to ideal sinusoidal waveform. Advanced IGBTs and snubber circuits can be employed in the design of the driver to obtain high performance with a simultaneous reduction in THD (total harmonic distortion) and torque ripple of the motor. The proposed concept offers a significant decreasing for driver harmonics compared to classical SVPWM used. The inverter can be operated in 3-phase and 20 kHz switching frequency. A PMSM motor is operated at 3kW and 48V with the proposed model is evaluated via simulation with a corresponding SVPWM (space vector pulse width modulation) method. Results of torque ripple and THD of the motor currents on the model are discussed.
