Linear optics modifications in order to improve injection efficiency and for the installation of two IDs in one straight section demand an optimization of the sextupole correction scheme. Four harmonic sextupole families were sufficient with the earlier 8-fold symmetric lattice. Today there are ten families of harmonic sextupole magnets in addition to the three families of chromatic sextupoles....

The problem addressed in this paper is how to restore the power taken by the current injection network in the case of optimal injection of third harmonic, in a simple way, providing self-adjustment of the rectifier to the load current variations. Goals of the presented research are to use only one current sensor, and to improve third harmonic injection technique. A new rectifier topology is pro...

The effects of optical injection locking on the nonlinear distortions of directly modulated semiconductor distributed feedback (DFB) lasers are investigated experimentally. The second harmonic distortion (SHD) and third harmonic distortion (THD), as well as the third-order intermodulation distortion (IMD3), are measured as functions of modulation frequency for both the free-running and injectio...

1 Introduction Harmonic resonance, subharmonic and superharmonic entrainment, quasiperiodic and chaotic behavior are well known to occur in nonlinear self-oscillating systems which are subject to periodic forcing. Harmonic resonance occurs if the periodic forcing signal has a frequency very similar to the one of the undisturbed system and results in an amplification of the oscillations.

One advantage of multi-phase machines is the possibility to use the third harmonic of the rotor flux for additional torque generation. This effect can be maximized for Permanent Magnet Synchronous Machines (PMSM) with a high third harmonic content in the magnet flux. This paper discusses the effects of third harmonic current injection (THCI) on a five-phase PMSM with a conventional magnet shape...

In recent years, harmonic current levels have increased in residential distribution networks due to the growing penetration of nonlinear loads at customer premises. To properly model injection residences, probabilistic models that account for stochastic behavior domestic are needed. As a part study reported this paper, field measurement campaign was performed 24 dwellings during one-week period...

This paper discusses the design and analysis of a high-harmonic injection-based field excitation scheme for brushless operation wound synchronous machines (WFSMs) in order to achieve higher efficiency. The proposed involves two inverters. One these inverters provides three-phase fundamental-harmonic current armature winding, whereas second inverter injects single-phase i.e., 6th harmonic this c...
