27-level converter for electric vehicles using only one power supply
(IEEE, 2010)
The main advantage of asymmetrical multilevel inverters is the optimization of levels with a minimum number of power supplies. However, this optimized multilevel system still needs a large number of isolated and floating ...
Multifunctional current reference generation strategy for grid-tied power electronic converter
(2015)
In this work the functionalities of Power Electronic Converters (PEC) used as grid interface device for distributed generation sources are extended to deal with Power Quality (PQ) issues. It is proposed an alternative ...
Reactive Power Limits in Distributed Generators from Generic Capability Curves
(2014-07-27)
This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal ...

Vector control of a modular multilevel matrix converter operating over the full output-frequency range
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 1982-2012 IEEE. The modular multilevel matrix converter (M 3 C) 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 ...
Uma aplicacao da celula de comutacao ZVS-PWM-GEPAE ao conversor DC-AC
(1996-05-01)
This work presents the design and procedure of a DC-to-AC converter using a ZVS Commutation Cell developed by Barbi and Martins (1991) and applied to the family of DC-to-DC PWM converters. Firstly, we show the cell applied ...
