Design of a novel modular energy conversion scheme for DC offshore wind farms
(IEEE, 2015)
Offshore wind farms provide benefits over onshore farms in terms of the amount of generated energy and environmental impact. Cost efficient energy transmission is one of the challenges of those installations. In this context ...
Analysis, comparison and selection of DC-DC converters for a novel modular energy conversion scheme for DC offshore wind farms
(IEEE, 2015)
Offshore wind farms provide benefits over onshore farms in terms of the amount of generated energy and environmental impact. Cost efficient energy transmission is one of the challenges of such installations. In this context, ...
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. ...
Series connection of power semiconductors for medium voltage applications
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2009)
The series connection of power semiconductor devices allows the operation at voltage levels higher than the levels allowed by one single semiconductor. However, due to individual parameter differences of the series connected ...
Multi-Objective Comparative Analysis of Active Modular Rectifier Architectures for a More Electric Aircraft
(MDPI, 2022)
Aircraft electrification requires reliable, power-dense, high-efficient, and bidirectional rectifiers to improve the overall performance of existing aircrafts. Thus, traditional bulky passive rectifiers must be substituted ...
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, ...
Static Current Unbalance of Paralleled SiC MOSFET Modules in the Final Layout
(IEEE, 2020)
Silicon Carbide (SiC) MOSFETs enable enhanced performance of power converters in several applications. Parallel connection of SiC MOSFETs become mandatory for medium power applications due to the current rate of existing ...
