Novel DC-link voltage variation method for interior permanent magnet synchronous motor drive system with high-efficient DC-DC converter

In this paper, a novel DC-link voltage variation method using a high-efficiency dc-dc converter for the three-phase-inverter of IPMSM (Interior Permanent Magnet Synchronous Motor) is proposed. The proper variation method of DC-link voltage is needed to reduce the torque ripple of IPMSM and, switchin...

Summary:In this paper, a novel DC-link voltage variation method using a high-efficiency dc-dc converter for the three-phase-inverter of IPMSM (Interior Permanent Magnet Synchronous Motor) is proposed. The proper variation method of DC-link voltage is needed to reduce the torque ripple of IPMSM and, switching loss of the inverter. Also, to meet the high-efficiency requirement of the DC-DC converter with the proposed method and, regenerative operation requirements of the motor-driver, a novel DC-DC converter is proposed. Simulation results are given to verify the reliability of the proposed DC-link variation method and DC-DC converter.
