    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

  3. 2. Analysis and Performance Evaluation of a Three-phase Three-level Sparse Neutral Point Clamped Converter for Industrial Variable Speed Drives

    Abstract : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. READ MORE

  4. 3. Performance Evaluation of Medium-Power Voltage Inverters

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Author : Emil Häger; [2015]
    Keywords : Inverter; neutral-point clamped; SPWM; switching losses; input ripple; total harmonic distortion;

    Abstract : Power inverters, used to convert DC power to AC, are often used in e.g. solar power applications. However, they tend to be impractically large and expensive; as such, power miniaturization is an active research area. READ MORE
