  3. 2. High-Frequency Voltage Distribution Modelling of a Slotless PMSM from a Machine Design Perspective

    University essay from KTH/Elkraftteknik

    Author : Patrik Brauer; [2018]
    Keywords : Windings; drives; transients; surges; steep-fronted; slotless; litz-wire; effective relative permeability; Lindningar; elektriska drivlinor; transienter; spänningspulser; litz-tråd; effektiv relativ permeabilitet;

    Abstract : The introduction of inverters utilizing wide band-gap semiconductors allow for higher switching frequency and improved machine drive energy efficiency. However, inverter switching results in fast voltage surges which cause overvoltage at the stator terminals and uneven voltage distribution in the stator winding. READ MORE

  4. 3. Do public and private firms show different reporting behaviour? A study of financial reporting quality in a Swedish setting

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : Marcus Litz; Jonas Henriksson; [2015]
    Keywords : financial reporting quality; earnings management; public versus private companies; opportunism; information demand;

    Abstract : Managers of companies have considerable influence over financial reports and may engage in earnings management, with lower financial reporting quality (FRQ) as a consequence. We provide a study of FRQ in Swedish public and private firms to identify if there exists differences between these groups' reporting behaviour, and if so, which characteristics that are indicative of such.
