DC-link Voltage Balancing Strategy based on SVM and Reactive Power Exchange for a 5L-MPC Back-to-Back Converter for Medium Voltage Drives
(IEEE, 2016)
The reduced capability of multilevel converters with more than one intermediate node to balance the dc-link capacitors voltage, as well as the lack of standard modulation methods to improve their balancing performance, ...
Simple voltage balancing method to protect series-connected devices experimentally verified in a 5L-MPC converter
(IEEE, 2018)
This paper presents a solution for the voltage balance problem of the series-connected devices that can be applied to multilevel converters in which the series-connected devices need to block twice their switched voltage. ...
A Performance Study of a Horizontal-axis Micro-turbine in a Numerical Wave Flume
(Elsevier Ltd., 2017)
Numerical studies of performance of a 3-bladed Savonius type horizontal-axis wave energy converter are presented. Numerical simulations based on a volume of fluid (VOF) method coupled with a finite volume method (FVM) ...
Hardening prediction of diverse materials using the Digital Image Correlation technique
(Elsevier, 2018)
In recent years, due to the introduction of higher resistance materials in the automotive sector, sheet metal-forming tool-makers have been forced to deal with more challenging process designs. Therefore, the optimisation ...
Fe nanoparticles produced by electric explosion of wire for new generation of magneto-rheological fluids
(IOP Publishing, 2018)
Iron magnetic nanoparticles were produced by the technique of the electric explosion of a wire (EEW). The major crystalline phase (95 ± 1%) was α-Fe with lattice parameter a = 0.2863(3) nm. The size of the coherent diffraction ...
