Control of the Modular Multilevel Matrix Converter for Wind Energy Conversion SystemsControl of the modular multilevel matrix converter for wind energy conversión systems
(2017)
The nominal power of single Wind Energy Conversion Systems (WECSs) has been steadily growing,
reaching power ratings close to 10 MW. In the power conversion stage, medium-voltage power
converters are replacing the ...
Control of wind energy conversion systems based on the modular multilevel matrix converter
(IEEE Institute of Electrical and Electronics Engineers, 2017)
The nominal power of single wind energy conversion systems (WECS) has been steadily increasing, now reaching power ratings close to 10 MW. In the power conversion stage, medium-voltage power converters are replacing the ...
Performance enhancement of switched affine systems by switched quadratic Lyapunov functions: Applications in DC-DC converters
(2013-01-01)
This paper proposes design methodologies to include the convergence rate to Switched Affine Systems, intending to reduce the current overshoot in DC-DC converters. The initial step consists in finding Lyapunov matrices for ...

Predictive Current Control With Instantaneous Reactive Power Minimization for a Four-Leg Indirect Matrix Converter
(2017)
This paper presents the experimental validation of a predictive current control strategy with minimization of the instantaneous reactive input power for a Four-Leg Indirect Matrix Converter (4Leg-IMC). The topology includes ...
The Application of the Modular Multilevel Matrix Converter in HighPower Wind Turbines
(2016)
The trend in wind turbines has shown an ongoing power rating growth, reaching sizes up to 10 MW.
Multilevel converters have therefore become a favourable solution for Multi-MW Wind Energy
Conversion Systems (WECSs), due ...
Vector control of a modular multilevel matrix converter operating in the full output-frequency range
The Modular Multilevel Matrix Converter M3C ) is an ac-to-ac converter topology suitable for the control of high-power variable-speed drives. The control of this converter is complex, particularly when the two ac system ...
