Multiple current amplifier-based gate driving for parallel operation of discrete SiC MOSFETs
(Wiley, 2022-03)
The shorter switching times of silicon carbide (SiC) MOSFETs enable power converters to operate at higher frequencies than with silicon IGBTs. However, because SiC MOSFET die sizes are still relatively small, several devices ...
Ibilgailu elektrikoaren joera: 2030a helburu
(Elhuyar, 2021)
Geroz eta ibilgailu elektriko gehiago ikusten ditugu kaleetan eta telebistako iragarkietan. Baina zenbat itxaron behar dugu ibilgailu elektriko bat erosteko? Errentagarriak dira? Merezi dute? Asko dira ibilgailu elektrikoaren ...
Common-Mode Voltage Elimination in Multilevel Power Inverter-Based Motor Drive Applications
(IEEE, 2022-01-07)
[EN] The industry and academia are focusing their efforts on finding more efficient and reliable electrical machines and motor drives. However, many of the motors driven by pulse-width modulated converters face the recurring ...
High-Voltage Stations for Electric Vehicle Fast-Charging: Trends, Standards, Charging Modes and Comparison of Unity Power-Factor Rectifiers
(IEEE, 2021-06-30)
Emission of greenhouse gases and scarcity of fossil fuels have put the focus of the scientific community, industry and society on the electric vehicle (EV). In order to reduce CO2 emissions, cutting-edge policies and ...
Effect of Symmetrically Switched Rectifier Topologies on the Frequency Regulation of Standalone Micro-Hydro Power Plants
(MDPI, 2021-05-30)
Micro-hydro power plants (μHPPs) are a major energy source in grid-isolated zones because they do not require reservoirs and dams to be built. μHPPs operate in a standalone mode, but a continuously varying load generates ...
Design and implementation of a droop control in d-q frame for islanded microgrids
(The Institution of Engineering and Technology, 2013-09-01)
The droop control method is usually selected when several distributed generators (DGs) are connected in parallel forming an islanded microgrid. This is because of the advantages it offers such as flexibility, absence of ...
General aspects, hierarchical controls and droop methods in microgrids: A review
(Elsevier, 2012-10-17)
Distributed generation is emerging as a new technology for supplying the increasing demand for electricity. Microgrids are attracting a great deal of attention since they integrate distributed generation in the main grid ...
Wide Bandgap semiconductor HF-oscillation attenuation method with tuned gate RLC filter
(IEEE, 2020-01-06)
Wide Bandgap (WBG) transistors provide better switching performance and higher operating temperatures compared to state of the art Si devices and are suited for high frequency applications due to very short switching times. ...
Interleaving Modulation Schemes in Asymmetrical Dual Three-Phase Machines for the DC-Link Stress Reduction
(MDPI, 2023-02-10)
The DC-Link capacitor plays a crucial role as far as power density and reliability are concerned: it occupies approximately 40% of the inverter, and causes approximately 30% of its failures. Asymmetrical dual three-phase ...
AC and DC technology in microgrids: a review
(Elsevier, 2014-12-05)
Microgrids are a suitable, reliable and clean solution to integrate distributed generation into the mains grid. Microgrids can present both AC and DC distribution lines. The type of distribution conditions the performance ...
