Harmonic Current Suppression of Dual Three-Phase Permanent Magnet Synchronous Motor with Improved Proportional-Integral Resonant Controller

open access: yesEnergies
The impedance of the harmonic plane in a dual three-phase permanent magnet synchronous motor (DTP-PMSM) is very low, meaning that even small harmonic voltages can induce significant harmonic currents, particularly at the fifth and seventh harmonic ...

Improved Performance of Low-Frequency Harmonic Current Suppression Based on Hybrid Active Power Filter

open access: yesEnergies
The hybrid active power filter (HAPF) can effectively suppress the 75–125 Hz low-frequency harmonic current generated by the EAST poloidal field power supply. However, the low-frequency harmonic current suppression performance of HAPF is greatly affected

Implementation of Current Harmonic Suppression for Imbalance in Six-Phase Permanent Magnet Synchronous Motor Drives

open access: yesEnergies
Current harmonics in six-phase permanent magnet synchronous motors (PMSMs) arise from inherent asymmetries caused by manufacturing tolerances and nonlinear characteristics in the inverter output. Additionally, magnetic saturation and slight imbalances in

A hybrid active filter for damping of harmonic resonance in industrial power systems [PDF]

open access: yes, 1998
This paper proposes a hybrid active filter for damping of harmonic resonance in industrial power systems. The hybrid filter consists of a small-rated active filter and a 5th tuned passive filter.

Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]

open access: yes, 2012
We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...
