A new approach for teaching power electronics in electrical engineering courses
(2015-01-01)
This work presents a new approach for teaching activities at the Laboratory of Power Electronics, at the Undergraduate Electrical Engineering course of the Faculty of Engineering Bauru (UNESP). The proposal is to develop ...
PWM Method to Eliminate Power Sources in a Non-Redundant 27-Level Inverter for Machine Drive Applications
(IEEE, 2006)
A non-redundant, three-stage, 27-level inverter using "H" converters, is analysed for machine drive applications. The main advantage of this converter is the optimisation of levels with a minimum number of semiconductors. ...
Current controller for a bidirectional boost input stage equipped with an LCL (inductance-capacitance-inductance) filter
(Elsevier, 2015-05)
A control strategy for a low resonance frequency LCL filter used in the input stage of dc-dc bidirectional boost converters is proposed. When compared with the classical L filter, an LCL filter allows to obtain a cheaper ...
Estudo e aplicação dos controladores Pi, Pi+R, preditivo e repetitivo em um sistema fotovoltaico conectado à rede elétrica monofásica
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2017-11-29)
This work presents a comparative study of the PI, PI + Resonant, PI + Repetitive and Predictive controllers, applied to a dual-stage photovoltaic system (PV) connected to a single-phase power grid. The PV system is composed ...
Phase-Shifted Model Predictive Control to Achieve Power Balance of CHB Converters for Large-Scale Photovoltaic Integration
(2020)
Cascaded H-Bridge (CHB) converters are attractive candidates for next generation photovoltaic (PV) inverters. CHB converters present a reduced voltage stress per power switch and a high modularity. Therefore, the plant can ...
Continuation power flow considering area net interchange constraint
(2015-01-01)
Interconnected power systems not only allow to the areas to provide mutual assistance, but also import or export energy with respect to optimize energy resources assessment where, a cost reduction involved in the generation ...
Robust Design of a Linear Quadratic Power Control Algorithm in Multiple-Access Networks
(2019)
In wireless networks under interference, power control is of the utmost importance to guarantee Quality of Service during data transmissions. A distributed perspective is commonly preferred to design controllers in each ...
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 ...
