Generalized suzuki-type mappings in modular vector spaces

Optimization, 2019
Very recently, a new type of generalized nonexpansive mappings on Banach spaces was introduced as an extension for the nonexpansiveness condition of Suzuki.

A new space-vector selector modulation for the modular multilevel converter applications

2020 IEEE XXVII International Conference on Electronics, Electrical Engineering and Computing (INTERCON), 2020
In this paper is proposed a new modulation technique for the modular multilevel converter, based on space vector theory. This technique is based on step-wave modulation (reduced switching frequency). Therefore, this technique performs a fast calculation of every pulse pattern of upper and lower arm three-phase voltages that will define the switching ...

An optimized control strategy for the modular multilevel converter based on space vector modulation

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
This 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 ...

On statistical convergence in modular vector spaces

2022
Let $X$ be a real vector space and $\rho: X\rightarrow [0, \infty]$ be a convex modular. The modular space generated by a convex modular $\rho$ is denoted by $X_\rho$, and is defined as follows: \[ X_\rho=\big\{x\in X: \lim_{u\rightarrow0+}\rho(ux)=0\big\}.

Hybrid Interleaved Space Vector PWM for Ripple Reduction in Modular Converters

IEEE Transactions on Power Electronics, 2011
This 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, 2012
The 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.
