Modular Multilevel Converter Based Topology for High-Speed, Low-Voltage Electric Drives
(IEEE-Inst. Electrical Electronics Engineers, 2020)
The increasing demand for higher power density and more efficient electric drives, in particular, from the automotive industry, has pushed engineers investigating new solutions. Recently, wide bandgap devices have been ...
Modelling and Control of the Modular Multilevel Converter in Back to Back Configuration for High Power Induction Machine Drives
(2016)
Drives based on modular multilevel topologies are
the next generation of high-power/voltage converters. In this
paper, the Modular Multilevel Converter model is extended to the
Back to Back scheme, allowing its control as ...
Simplified Small-Signal Model for Output Voltage Control of Asymmetric Cascaded H-Bridge Multilevel Inverter
(Ieee-inst Electrical Electronics Engineers Inc, 2018-04-01)
This paper proposes a simplified small-signal model for output voltage control of a single-phase asymmetrical cascaded H-bridge multilevel inverter (ACHMI). The ACHMI is an n-series connected H-bridge converter, each one ...

Circulating current control for the modular multilevel matrix converter based on model predictive control
(IEEE-Inst. Electrical Electronics Engineers, 2021)
In this work, a continuous-control-set model predictive control (CCS-MPC) strategy, with a saturation scheme for protection, is presented for regulating the circulating currents of a modular multilevel matrix converter ...
Estimating the concentration of gold nanoparticles incorporated on natural rubber membranes using multi-level starlet optimal segmentation
(Springer, 2014-12-01)
This study consolidates multi-level starlet segmentation (MLSS) and multi-level starlet optimal segmentation (MLSOS) techniques for photomicrograph segmentation, based on starlet wavelet detail levels to separate areas of ...
A WTS Power Conversion Stage With Multilevel Converters Operating in the Medium Voltage Range
(Pergamon-Elsevier Science Ltd, 2012-07)
A high power medium voltage converter for wind turbine system is presented in this paper. The proposal mitigates classic design tradeoffs around low voltage, high current link between the generator and the utility grid on ...
Multi-level pedagogical model for the personalization of pedagogical strategies in intelligent tutoring systems
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-11-01)
Pedagogic strategies are action plans designed to manage issues related to sequencing and content organization, specifying learning activities, and deciding how to deliver content and activities in teaching processes. In ...
