  5. 19. Simulation and Analysis of a Power Supply Circuit for Frequency Inverter Controlled AC-Induction Motors

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Meike Stemmann; [2009]
    Keywords : Technology and Engineering;

    Abstract : For variable-frequency drives, the most common way to apply the desired power to an electrical motor is using PWM modulated signals. Due to high-frequency components, those signals give rise to reflections in the motor cables, radiated noise around the cables and acoustic noise in the motor. READ MORE
