A Licentiate's degree conprises 120 ECTS credits, of which atleast 60 ETCS credits constitute a Licentiate's thesis.

Technical Review and Survey of Future Trends of Power Converters for Fast-Charging Stations of Electric Vehicles

“…The power demands of a DC fast-charging station require a significant amount of power, which can easily exceed megawatts. Thus, recently, modular multilevel converters (MMCs) have become more popular compared to other multilevel topologies for medium/high voltage and high-power applications such as DC fast-chargers [77][78][79][80][81][82][83][84][85]. The reasons that MMCs are the preferred choice in medium/high voltage high-power applications include their modular and scalable structure, which can meet any voltage level requirements by using medium-voltage devices, as well as their lowering of voltage distortion and creation of more sinusoidal waveforms [78], superior harmonic performance [78], increased fault tolerability [84], and higher efficiency [86,87].…”
