selective harmonic elimination (she) is a powerful modulation scheme aims to find the required switching angles in order to eliminate the number of undesired harmonics. she is a complicated problem which consists of several nonlinear equations which have multiple local minima. in order to eliminate the higher number of undesired harmonics and as a result reducing the total harmonic distortion (...

The simple Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI) is presented here. The proposed work is to examine the Selective Harmonic Elimination (SHE) and to eliminate harmonics produced by Pulse Width Modulation (PWM) inverter. The selective harmonic elimination method for three phase Voltage Source Inverter (VSI) is generally based on ideas of opposite harmonic ...

The harmonic currents are generated by single phase nonlinear loads. The mirror surplus harmonic elimination method is used mostly because of its less computation. The Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) based methods can provide theoretically the highest quality output among all the PWM methods. In this paper SHEPWM model of a multilevel series connected voltage sour...

Pulse Width Modulation (PWM) techniques are increasingly employed for PWM inverter fed induction motor drive. Among various popular PWM methods used, Selective Harmonic Elimination PWM (SHEPWM) has been widely accepted for its better harmonic elimination capability. In addition, using SHEPWM, it is also possible to maintain better voltage regulation. Hence, in this paper, an attempt has been ma...

-Selective harmonic elimination/control (SHE) has been a widely researched alternative to traditional pulse-width modulation technique. It has been a research topic since the early 1960’s and developed into a mature form during the 1970’s. This report will discuss the generalized techniques of selective harmonic elimination developed in [1] during 1973. And work focus on simulating the results ...

This work considers new applications of Firefly and Fireworks algorithm for solving the selective harmonic elimination problem in inverter output waveforms. The higher order harmonics in the output of the inverter can be eliminated easily by using small passive filters. Lower order harmonic elimination requires selecting a pre-specified firing angle. That angle is one of the many solutions of a...
