  1. 1. 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

  2. 2. Simulation of a Current Controller with Dead-Time Compensation

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Author : Johanna Heide; Mattias Granström; [2021]
    Keywords : control theory; simulation; current controller; dead-time; dead-time compensation; pmsm; c-caller; linköping university; ABB;

    Abstract : This master's thesis is divided into two parts. The first part concerns the development of a simulation model of a current controller and a physical drive unit, both implemented in Simulink with the use of legacy code and regulated with field oriented control. The second part concerns the development of a dead-time compensation algorithm. READ MORE

  3. 3. Optimization and Up-Gradation of 3-Phase Half-Bridge Inverter Board

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Keywords : Inverter; Half Bridge; PCB; AC; Power Electronics; SiC; Power MOSFET; Gate Drive; Snubbers; Bootstrap; Ringing; DC to AC; Power Conversion;

    Abstract : Solar Bora AB is a Linköping based company that provides end to end solution for clean and reliable energy. System developed by them generates high power 230V AC to run electrical appliances. READ MORE

  4. 4. Real-time detection of stator resistance unbalances in three phase drives

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

    Author : Bhanu Pratap Singh; [2020]
    Keywords : DC voltage injection; Fault detection; Field-Oriented Control; Induction machine; Inter-Turn Short Circuit; Short circuit; Sequence; Stator resistance unbalance; Symmetrical components; likspänningsinjektion; feldetektering; fält orienterad reglering; induktionsmaskin; InterTurn Short Circuit; kortslut; sekvenser; statormotstånd obalans; symmetriska komponenter;

    Abstract : An estimated 30% of the faults in Induction Machine (IM) are related to its stator. These faults are mostly in the form of an Inter-Turn Short Circuit (ITSC) fault i.e., when two winding inside the stator of IM are shorted due to insulation failure. READ MORE

  5. 5. Electrohydraulic Power Steering Simulation : Dynamic, thermal and hydraulic modelling

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

    Author : Oskar Svensson; [2019]
    Keywords : PMSM; SVPWM; vector control; FOC; lumped parameter model; LPM; hydraulic pump; simulation;

    Abstract : There are several benets of electrohydraulic power steering systems, as compared to hydraulicpower steering systems where the pump is driven directly by the engine of the vehicle. Someof these benets are increased eciency and improved steering performance. READ MORE
