RÉTROACTION DE COURANT D'AMPLIFICATEUR DE CLASSE D

摘要

The technology described in this document can be embodied in an audio power amplifier that includes a pair of switching devices, drive circuitry for driving the pair of switching devices to produce a signal, and an output filter to filter the signal from the pair of switching devices. The output filter is configured to provide the filtered signal to an audio load. The audio power amplifier includes a voltage feedback loop to provide a voltage of the filtered signal to a voltage controller of the audio power amplifier, and a current feedback loop to provide a current of the filtered signal to a current controller of the audio power amplifier.
