Comparison between selective harmonic elimination and nearest level control for transistor clamped H-bridge inverter [PDF]
Indonesian Journal of Electrical Engineering and Computer Science, 2022 Total harmonic distortion (THD) is a key index used to measure the quality of output waveforms in multilevel inverters. In this paper the THD is investigated and compared between two modulation methods; selective harmonic elimination and nearest level ...

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 ...
