Design of Controller for Selected Harmonic Power Elimination from DC Bus in Single Phase Inverter

IEEE International Conference on Power Electronics, Drives and Energy Systems, 2018
Single phase power converters operating in standalone mode, has to frequently supply the non-linear loads. Under such case, the power reflected onto the DC bus, contains harmonics other than the usual double-frequency component. This increases the stress

FPGA-Based Unit for Selective Harmonic Elimination in Voltage-Source Inverters

2024 IEEE 22nd Mediterranean Electrotechnical Conference (MELECON)
Many electric drives, such as railway traction machines, are designed to be operated in an overmodulation region and in six-step mode, where the motor voltage waveform is distorted by low-order harmonics.

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 modulation method for multilevel inverters

2006 India International Conference on Power Electronics, 2006
Multilevel converter technology has recently emerged as a very important alternative in the area of high-power applications. Several modulation methods have been applied to multilevel Inverters. The modulation methods with higher switching frequency reduce filter size but increases switching losses.

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.

Selective harmonic elimination in seven level cascaded inverter

2013 International Conference on Renewable Energy and Sustainable Energy (ICRESE), 2013
This paper aims to extend the knowledge about the implementation of selective harmonic elimination in cascaded multilevel inverter to eliminate the specified harmonics in the output voltage. An optimization technique is proposed to compute switching angles at fundamental frequency switching scheme by solving non-linear transcendental equations (known ...
