摘要:Summary(#br)An enhanced level‐increased nearest level modulation (eNLM) method is proposed to improve the performance of modular multilevel converter (MMC) with relatively small number of submodules. The eNLM method can almost double the level number of ac output voltage, ...

摘要:Characteristics of equivalent area method of the nearest level modulation (NLM) is analysed in detail and an improved NLM for ten or so cells of cascaded H-bridge (CHB) converter with a high modulation precision is proposed. The proposed algorithm can make the output voltage of t...

摘要:This study focuses on the possibility of modular multilevel converter (MMC) loss optimisation by modulation without any additional circuit, where a common-mode voltage is injected into a nearest level modulator. Owing to the common-mode voltage injection, the proposed modulation ...

摘要:In this paper, a hybrid modular multilevel converter (MMC) topology with an improved nearest level modulation method is proposed for medium-voltage high-power applications. The arm of the proposed topology contains N series connected half-bridge submodules (HBSMs), one full-bridg...

摘要:This work presents a comparison of three different modulation techniques applied to modular multilevel converters (MMCs). The three modulation strategies studied in this paper are the phase-shifted sinusoidal pulse width modulation (PS-SPWM), the space-vector modulation (SVM) and...

摘要:Power converters using deterministic pulse width modulation (PWM) schemes have discrete and high harmonics concentrated at well-defined frequencies. In this study, two random PWM strategies to reduce the harmonic spikes for multilevel cascaded H-bridge (CHB) inverters are propose...
