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 ...

Ibilgailu elektrikoen potentzia-bihurgailuen hozte-metodoak
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2017)
Ibilgailu elektrikoari loturiko potentzia-bihurgailuetan, korronte-dentsitate handitan (500 A ingurukoak) lan egiten duten IGBT transistoreak eta diodoak erabiltzen dira. Korronte altuak direla eta, handitu egiten dira ...
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 ...
