  1. 11. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Farhan Akram; [2021]
    Keywords : SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Abstract : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. READ MORE

  3. 12. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  4. 13. Tests of Series Arcing and Arc Fault Detection Devices in Low Voltage Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ghazal Al Qabbani; [2021]
    Keywords : ;

    Abstract : Unwanted electrical arcs are a concern in fire and electrical equipment safety. Arcs in electrical systems can be categorized into two main groups, traditionally called: Series and parallel arc faults, or more recently called low current and high current arc faults. READ MORE

  5. 14. Fault energy implications of distributed converter interfaced generation : A case study of an underground mine grid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tommy Hjertberg; [2021]
    Keywords : Dispersed PEID generators; short circuit energy; arc incident energy; protective relays; fault ride through; Distribuerad omformardriven generering; kortslutningsenergi; händelseenergi; reläskydd; felgenomkörning;

    Abstract : Adding Power Electronic Interfaced Devices (PEID) generation to grids is an increasing trend because of the concurrent development of better power electronic converters and a greater interest in a better utilisation of energy resources. Small and dispersed energy sources that would previously not be worth introducing into the grid is becoming more and more viable and other potential benefits such as better control of voltage levels and smoothing out load changes also spur this development.

  6. 15. Optimal torque split strategy for BEV powertrain considering thermal effects

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhananjay Yadav; [2021]
    Keywords : Optimal torque-split control strategy; battery electric vehicles; thermal model of electric machines; system identification; model order reduction; co-simulation.; Optimal vridmomentsdelningsstyrningsstrategi; batteridrivna fordon; termiska modeller av elektriska maskiner; systemidentifiering; minskning av modellorder; samsimulering.;

    Abstract : A common architecture for electric vehicles is to have two electric machines one each on the front and rear axle. Despite the redundancy, this configuration ensures performance. Being energy efficient is equally important for electric vehicles to deliver a sufficiently high range. READ MORE
