A large number of harmonics will be generated in the process transforming high frequency and voltage alternating current (AC) into a constant through power conversion system when high-speed motor is used as generator. The phase-shifting reactor to eliminate for generator systems, LCL filter adjustable inductance are supply this paper. can adjust value time according change output inverter. resu...

In this paper we are concerned with the elimination of gamma related errors by employing a simple and direct approach, specifically, for phase measuring profilometry (PMP) methods. The harmonic structure of a gamma distorted fringe is investigated and the implications of j for the PMP algorithm is studied. The minimum requirements in terms of number of Steps for appropriate elimination of j rel...

This paper presents the application of differential evolution algorithm to obtain optimal switching angles for a single-phase seven-level to improve AC voltage quality. The proposed inverter in this article is composed of two H-bridge cells with non-equal DC voltage sources in order to generate multiple voltage levels. Selective harmonic elimination pulse width modulation (SHPWM) strategy is us...

A highly integrated frequency quadrupler MMIC that uses three-dimensional MMIC (3D-MMIC) technology is presented. It consists of four driver amplifiers, two doublers, and a 2-band elimination filter. These seven circuits are integrated in only a 2.36 mm2 area. The filter sufficiently suppresses spurious output components. The third and fifth harmonic components, which are the spurious component...

This Paper aims to extend the knowledge about the performance of different cascaded multilevel inverter through harmonic analysis. Large electric drives and utility require advanced power electronics converter to meet high power demands. As a result, multilevel power converter structure has been introduced as an alternative in high power and medium voltage situations. A multilevel converter not...
