Isolated output system for a class D switching-mode amplifier
Abstract
A class D amplifier for the amplification of signals having unipolar or bipolar direct current, or alternating current is described. Positive and negative signal channels and a transformer-coupled output circuit for each channel are included. A switching circuit which effects isolation of the non-operating channel from the operating channel as a function of signal polarity is also described.
