1. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. READ MORE

2. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE

3. The role of location of low inertia in power systems
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

4. Quantifying Middle Frequency Transient Currents in Power Consuming Devices
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. READ MORE

5. Eliminating zero-missing phenomenon in long, high voltage, underground cables
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The maximum length of an high voltage underground cable (HV UGC) cable is oftenconstrained by the criterion that the cable cannot have more than 50% reactivepower compensation. If this limit is exceeded the current in the circuit breaker maynot have a zero crossing after energization, which is referred to as the zero missingphenomenon. READ MORE
