High Efficiency Audio Power Amplifiers

    Project Details

    Description

    By using switch-mode power electronics (class D, CoolPower) as an alternative to the classical class B audio power amplifiers it is possible to reduce the power dissipation and increase the efficiency without compromising the audio performance. This is done by using state-of-the-art analogue and digital control theory and signal processing in combination with high frequency power electronics. Furthermore research is done in multi-level PWM called PSCPWM - Phase Shifted Carrier Pulse Width Modulation.
