Unified Selective Harmonic Elimination for Multilevel Converters

IEEE Transactions on Power Electronics, 2017
For multilevel converters, as their selective harmonic elimination (SHE) equations are highly related to the switching patterns, it is almost impossible to give a complete study for all the switching patterns under the traditional SHE framework.

VSC Based D-STATCOM with Selective Harmonic Elimination

2007 IEEE Industry Applications Annual Meeting, 2007
This paper describes the design, implementation, and performance of a medium-size distribution-type static synchronous compensator (D-STATCOM) with the simplest two-level three-leg voltage-source converter (VSC) topology. Reactive-power control is achieved by phase-shift-angle control, and VSC harmonics are eliminated by selective harmonic elimination ...

Parallel resultant elimination algorithm to solve the selective harmonic elimination problem

IET Power Electronics, 2016
Although the resultant elimination method can get all the possible solutions for the selective harmonic elimination (SHE) problem without the selection of initial values, it still has some fatal shortcomings, such as the high computation burden and the huge memory consumption caused by the intermediate expression swell in the ...

Simple analytical solution for selective harmonic elimination technique

Electronics Letters, 2016
A new simple analytical and closed‐form solution for the harmonic content injected in the five‐level inverters at low switching control technique is proposed. The equations of the fundamental and the third harmonic are formulated and solved. The switching angles have been calculated to fix the fundamental voltage at a specified value and cancel the ...

A "nearly parametric" solution to Selective Harmonic Elimination PWM

, 2015
Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) is an important technique to solve PWM problems, which control the output voltage of an inverter via selecting appropriate switching angles. Based on the Rational Univariate Representation (RUR) theory for solving polynomial systems, the paper presents an algorithm to compute a "nearly ...

Selective Harmonic Elimination in Multimodule Three-Phase Current-Source Converters

IEEE Transactions on Power Electronics, 2010
Modular current-source converter (MCSC) structures can enhance the current capacity and improve the power quality of converters in medium-voltage pulsewidth-modulated applications. An MCSC uses individual three-phase modules in a shunt connection to share the total power in a symmetrical manner.
