Modified ADALINE algorithm for harmonic estimation and selective harmonic elimination in inverters

International Journal of Electronics, 2011
In digital signal processing, algorithms are very well developed for the estimation of harmonic components. In power electronic applications, an objective like fast response of a system is of primary importance. An effective method for the estimation of instantaneous harmonic components, along with conventional harmonic elimination technique, is ...

Three-phase multilevel inverter with selective harmonic elimination

2015 Workshop on Engineering Applications - International Congress on Engineering (WEA), 2015
This paper describes the design and develop of a common source three-phase multilevel power converter, with five levels in the phase voltage and nine levels in the line voltages. The modulation is optimized using genetic algorithms that perform a selective harmonics elimination of the first 20 components to improve power quality.

Selective Harmonic Elimination With Groebner Bases and Symmetric Polynomials

IEEE Transactions on Power Electronics, 2016
Selective harmonic elimination (SHE) technology has been widely used in many medium- and high-power converters which operates at very low switching frequency; however, it is still a challenging work to solve the switching angles from a group of nonlinear transcendental equations, especially for the multilevel converters. Based on the Groebner bases and

Selective harmonic elimination PWM technology applied in PMSMs

2012 IEEE Vehicle Power and Propulsion Conference, 2012
This paper introduces selective harmonic elimination PWM (SHEPWM) technology applied in PMSMs. According to model of PMSMs, relation between harmonic currents and voltages is derived. From this relation, selection principle of SHEPWM is different for salient pole PMSMs and non-salient pole PMSMs.
