Abstract: Permanent magnet motors offer high efficiency, fast start, strong overload capacity and low noise. Successfully applied to high-power AC drive systems, they face problems of slow dynamic torque response and large torque ripple from traditional Si converter's low switching frequencies. Leveraging silicon carbon (SiC) devices' high temperature resistance and high switching frequencies, this paper introduces a Si/SiC three-level active neutral-point-clamped (ANPC) inverter into permanent magnet motor drive systems. First by investigating the Si/SiC hybrid ANPC inverter's operating principle and commutation modes, we analyze loss distribution and modulation strategies under different commutation modes. We propose a high-and low-frequency decoupling predictive control strategy for the permanent magnet motor fed by the Si/SiC hybrid ANPC inverter based on model predictive control's multi-objective and multi-constraint characteristics. This achieves Si and SiC device low- and high-frequency operation, respectively. Steady state and transient experimental results verify the feasibility and effectiveness of the proposed control strategy.
