ABSTRACT:
An inverter for an audio amplifier. The inverter comprises a current damping feedback loop for actively damping oscillations caused by an output inductor within the inverter. A forward compensator is provided to compensate for the frequency response of the actively damped filter. The resulting inverter generates an output voltage that tracks an input voltage thereof with improved frequency response within the frequency range of interest.
