    Abstract : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. READ MORE

  3. 2. Efficiency Comparison between a Two-level and an NPC Inverter for Automotive Application

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

    Author : Simon Schneider; [2022]

    Abstract : De flesta nuvarande elfordon drivs med en systemspänning på 400V. En ökning av denna spänning skulle dock bland annat kunna möjliggöra en kortare laddningstid för fordonets batteri. Den högre systemspänningen medför ett antal utmaningar, varav en är att öka spänningsblockeringsförmågan hos spänningsomvandlarens transistorer. READ MORE
