Design and Analysis of a Five-Phase SPM Machine Considering Third Harmonic Current Injection
IEEE transactions on energy conversion, 2018This paper analytically derives the optimal third harmonic current to improve the output torque in five-phase surface-mounted permanent magnet (SPM) machines under the constraints of the same peak/rms value. The relationship between the output torque and

This paper presents a control method to reduce the radiated noise of permanent magnet synchronous machines. This is achieved by the superposition of harmonic currents in addition to those applied by field oriented control.

Time harmonic eddy currents in non‐linear media
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1998One way to deal with non‐linearity in the case of time harmonic excitation of the electric and magnetic fields in ferromagnetic media is to introduce an effective material to model the ferromagnetic region. This fictitious material is constant throughout a period but inhomogeneous and it takes into account the non‐linear relationship between the field ...

IEEE transactions on industrial electronics (1982. Print), 2018
To increase power rating, parallel-connected converters are widely used in power systems. However, it brings challenge to output harmonic current control. For active power filter, the harmonic current compensation performance worsens.

A modified harmonic current vector method for harmonic contribution determination
IEEE PES Power Systems Conference and Exposition, 2004., 2005This paper deals with the determination of customer contributions to harmonic distortion at the point of connection to the utility network. The approach proposed in this paper is derived from the common power factor practice where a load should be fully compensated at the fundamental frequency and therefore seen as resistive from the network.

ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics, 2002
Modern adjustable-speed, induction motor drives are responsible for contaminating electric networks with undesirable harmonics. Most of the speed controllers developed for induction motors employ a rectifier-inverter arrangement. In this arrangement, the alternating current drawn by the rectifier contains many undesirable harmonics. These harmonics may

Current induced second harmonic generation in semiconductors
Applied Physics Letters, 1995Direct current in semiconductor is theoretically shown to be capable of doubling the frequency of the incoming optical radiation. The second order susceptibility, proportional to the current is calculated to be in the 10−14−10−13 m/V range. Applications of the novel phenomenon in probing and mapping of the current in semiconductor devices are ...

Valuation of harmonic current injections
2002The number of power electronic and distorting loads, continue to grow at a rapid pace. Accompanying this growth in distortion sources is an increased sensitivity of certain types of loads to harmonic distortion, and poor power quality in general. The result is greater variance in the value loads place on a harmonic free supply, and therefore what they ...
