IEEE transactions on magnetics, 2021
In general, permanent magnet (PM) motors are driven by a pulsewidth modulation (PWM) voltage source inverter for vector control. The generated PWM signals cause high-frequency voltage components at the carrier frequency.

Current Harmonics Generated by Motor-Side Converter: New Standardizations
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021Pulsed width modulation (PWM) voltage generated by power converters creates current harmonics in the range of 2–150 kHz. To address the challenges created by these harmonics, new standards for harmonic emission within that frequency range is being ...

Reducing Supply Current Harmonics
IEEE Industry Applications Magazine, 1998In this article, a simple and effective method for reducing the supply current harmonics has been proposed for a parallel connected 12-pulse thyristor converter with an interphase reactor. The proposed method requires only an interphase reactor with an optimal inductance value being much smaller than conventional inductance values, without any ...

Proceedings of the IEEE International Conference on Industrial Technology (ICIT'96), 2002
New compensation method of specific number harmonics currents is proposed and its excellent compensation effects are explained in comparison with conventional versatile compensation. In addition, preference compensation of specific number harmonics currents is also proposed and experimental data with a small model proves the superiority of this method.

Non-harmonic alternating currents
Journal of the A.I.E.E., 1927Certain principles are presented for solving non-harmonic a-c. problems. Graphical methods are already well known for solving practically any problem, when currents and electromotive forces are sinusoidal, by vector diagrams in a plane. In certain special cases such diagrams give correct results when currents and electromotive forces are non-sinusoidal,

An Optimized Modulation of Torque and Current Harmonics Suppression for Dual Three-Phase PMSM
IEEE Transactions on Transportation ElectrificationAlthough dual three-phase permanent magnet synchronous motor (DTP-PMSM) exhibits smoother output torque compared to traditional three-phase PMSM, the limitation of switching frequency in high-power industrial equipment can cause a decrease in the carrier
