DC voltage balance based on zero sequence voltage is commonly used for star-connected cascaded H-Bridge (SCHB) STATCOM to compensate negative sequence current. However, zero sequence voltage injection brings about side-effect of increasing STATCOM output voltage and thus the Negative sequence Current Compensation Range (NCCR) is significantly limited ...

Grid Support During Asymmetrical Faults using Negative Sequence Current Injection
2019 IEEE 4th International Future Energy Electronics Conference (IFEEC), 2019This paper investigates the effect of injecting negative sequence reactive current into the grid in case of asymmetrical faults. In such conditions, the negative sequence voltage will increase and may cause instability in the system or damage to some equipment such as three phase rotating machines. Hence, the aim of this study is to support the grid by

Cascaded H-bridge STATCOM is widely adopted to regulate the power quality in power grid and industrial application. Considering the existence of zero-sequence voltage which cannot be neglected in the simulation model, this paper proposed an improved clustered voltage balancing strategy based on negative-sequence current injection.

Symmetrical Components Observer for LPMM Back EMF Based on Negative-Sequence Current Injection
IEEE Transactions on Industrial Electronics, 2022Thrust force ripple, including no-load detent force and electromagnetic thrust ripple, worsens the precision of the linear permanent magnet machine (LPMM) control system. This article focuses on the elimination of electromagnetic thrust ripple caused by the finite length of the LPMM mover core.

Due to the presence of full-bridge submodules (FBSMs), hybrid modular multilevel converters (HMMCs) consisting of FBSMs and half-bridge submodules (HBSMs) can work under the over-modulation conditions, which means that half of the dc voltage is less than the magnitude of the ac voltage.
