A Hybrid Calculation Method of Electromagnetic Vibration for Electrical Machines Considering High-Frequency Current Harmonics

IEEE transactions on industrial electronics (1982. Print), 2022
This article proposes a hybrid evaluation method of electromagnetic force and vibration for electrical machines considering high-frequency current harmonics caused by the inverter. First, the permeance and armature magnetomotive force (MMF) is calculated

Multiple Current Harmonics Suppression for Low-Inductance PMSM Drives With Deadbeat Predictive Current Control

IEEE transactions on industrial electronics (1982. Print), 2022
Inverter nonlinearity and nonsinusoidal back electromagnetic forces (EMFs) can cause large current harmonics in permanent magnet synchronous machine (PMSM) drives, especially for those with low inductance, resulting in increased torque ripples and losses.

Suppression of Major Current Harmonics for Dual Three-Phase PMSMs by Virtual Multi Three-Phase Systems

IEEE transactions on industrial electronics (1982. Print), 2021
Dual three-phase (DTP) permanent magnet synchronous machine (PMSM) systems exhibit high current harmonics due to low impedance to voltage disturbance such as inverter voltage errors and back-EMF harmonics. This article proposes a concept of virtual multi

Current Harmonics Generated by Multiple Adjustable-Speed Drives in Distribution Networks in the Frequency Range of 2–9 kHz

IEEE transactions on industry applications, 2022
Adjustable-speed drives (ASDs) generate current harmonics due to their nonlinear characteristic and switching function. These current harmonics could pass through a network and deteriorate the power quality, create resonances, and increase network power ...

PMSM Current Harmonics Control Technique Based on Speed Adaptive Robust Control

IEEE Transactions on Transportation Electrification, 2022
The permanent magnet synchronous motor (PMSM) is widely used in electric vehicles due to its high power density. New requirements are constantly proposed with the development of PMSM, one of which is torque ripple.

Multistage Predictive Current Control Based on Virtual Vectors for the Reduction of Current Harmonics in Six-Phase PMSMs

IEEE transactions on energy conversion, 2021
The most recent finite control set model predictive control (FCS-MPC) strategies for six-phase electric drives avoid the excitation of the secondary subspace by using virtual vectors to minimize the current ripple.

Compensation of Selective Current Harmonics for Switching-Table-Based Direct Torque Control of Dual Three-Phase PMSM Drives

IEEE transactions on industry applications, 2021
Current harmonics are ubiquitous in dual three phase (DTP) permanent magnet synchronous machine (PMSM) drives. Due to back electromotive force (EMF) distortion, significant current harmonics are generated in the DTP-PMSM system. The influence of back EMF

Harmonics in opposed current converters

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
Practical switching devices have finite turn-on and turn-off times. Normally a blanking time is added between the turn-off and turn-on of switches to avoid a short circuit during switching. This blanking time results in a current dependent voltage error of the pulse width modulated output of a converter.

Model-Predictive Current Control Scheme for Seven-Phase Voltage-Source Inverter With Reduced Common-Mode Voltage and Current Harmonics

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
This article presents a simple model-predictive current control (MPCC) scheme to reduce both the common-mode voltage (CMV) and current harmonics for a two-level seven-phase voltage-source inverter (VSI).
