Optimal Harmonic Mitigation in Distribution Systems with Inverter Based Distributed Generation
In recent years, with the widespread use of non-linear loads power electronic devices associated with the penetration of various renewable energy sources, the distribution system is highly affected by harmonic distortion caused by these sources. Moreover,

Analytical model for calculating the nonlinear distortion in silicon-based electro-optic Mach-Zehnder modulators [PDF]
In this study, an analytical model for calculating the nonlinear harmonic/intermodulation distortion for RF signals in silicon-based electro-optic modulators is investigated by considering the nonlinearity on the effective index change curve with the ...

A NEW STRUCTURE OF FIVE-LEVEL DIODE CLAMPED INVERTER WITH REDUCING ITS ELEMENTS
At the high power switching circuit's applications, when the harmonic distortion is harmful, a multi-level diode clamped inverter is useful, especially when reduced total harmonic distortion and high power are desired.

An approach to harmonic load- and source-pull measurements for high-efficiency PA design [PDF]
High-efficiency power-amplifier design requires numerous efforts to investigate both input and output harmonic terminations effects. A simplified theoretical approach to clarify the relevance of such terminations is presented here, and design criteria to

MSSB to Prevent Cable Termination Faults for Long High Voltage Underground Cable Lines
Cable termination fault is one of the most important problems for high voltage underground cable lines (HVUCL). Harmonic current (HC) and the sheath current (SC) are causes of cable termination faults of HVUCL.

Behavior of single-point harmonic producer indicators in electrified AC railways [PDF]
Electrified railways are an example of AC single phase distribution networks. A non-negligible amount of active and nonactive power may be related to harmonics, especially for distorted highly-loaded systems.
