IEEE Journal of Emerging and Selected Topics in Power ElectronicsConventional harmonic suppression strategies determine compensating voltages by extracting current harmonics while neglecting the motional electromotive force harmonics (MEMFHs) induced by speed fluctuations. Especially for low-inertia permanent magnet synchronous motors (PMSMs), current harmonics and speed fluctuations exhibit strong coupling, and ...

Current Control System of Hybrid Converter for Suppressing Current Harmonics
2021 IEEE International Electric Machines & Drives Conference (IEMDC), 2021The driving electric machine of high-power flywheel energy storage system (FESS) has the characteristics of high fundamental frequency and low inductance, which lead to high current harmonic content and increases the loss of FESS. To suppress the current harmonics, a compound control scheme is proposed for an innovative hybrid converter in this paper ...

Adaptive current harmonics suppression strategy for grid-tie inverters
ISA Transactions, 2022Since the observed angle of a phase-locked loop (PLL) is relatively accurate even under distorted grid conditions, the mathematical model of the voltage errors caused by the switching modulation and the dead-time effect are derived as a function of the grid voltage angle in this paper.

Suppression of the 5th and 7th current harmonics of an IPMSM
2013 15th European Conference on Power Electronics and Applications (EPE), 2013This report presents an extension of the Field Oriented Control technique to suppress the 5th and the 7th current harmonics of an IPMSM. The influence of the current harmonics on the fundamental control loop is analyzed and a proposition for their identification is given. Two additional control loops - in parallel with the fundamental control loop-have
