Hybrid Interleaved Space Vector PWM for Ripple Reduction in Modular Converters
IEEE Transactions on Power Electronics, 2011This paper addresses the problem of optimizing space vector PWM (SVM) for interleaved, parallel-connected, three-phase voltage source converters to reduce total harmonic distortion (THD) of the total line current. A systematic approach is presented for designing hybrid SVM schemes involving multiple sequences, including those based on active state ...

A three-level indirect space vector modulation scheme for multi-modular matrix converters
2012 IEEE International Symposium on Industrial Electronics, 2012The multi-modular matrix converters (MMMCs) constructed with three-phase to single-phase matrix converter modules have emerged as a viable topology candidate for high-power applications. Due to the three-to-two module structure and elimination of dc components, modulation scheme design for the MMMCs is not straightforward at first glance.

Amenability and Fixed Point Properties of Semitopological Semigroups in Modular Vector Spaces
Canadian Mathematical Bulletin, 2019AbstractIn this paper, we initiate the study of fixed point properties of amenable or reversible semitopological semigroups in modular spaces. Takahashi’s fixed point theorem for amenable semigroups of nonexpansive mappings, and T. Mitchell’s fixed point theorem for reversible semigroups of nonexpansive mappings in Banach spaces are extended to the ...

Space vector-based modeling and control of a modular multilevel converter in HVDC applications
2013 15th European Conference on Power Electronics and Applications (EPE), 2013Modular multilevel converter (MMC) is an emerging multilevel topology for high-voltage applications that has been developed in recent years. In this paper, the modeling and the control of MMCs are restated in terms of space vectors, which may allow a deeper understanding of the converter behavior.

An optimized control strategy for the modular multilevel converter based on space vector modulation
2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015This paper proposes an optimized control strategy for any modular multilevel converter (MMC), based on a generalized space vector modulation (SVM) method. By fully utilizing the flexibility of the SVM method, i.e., the redundant switching sequences and adjustable duty cycles, this optimized control strategy enables optimal capacitor-voltage and ...
