Class D Amplification;

Thanks to digital technology; yet another more efficient circuit architecture has become available. This is called Class D and can be considered as being similar to a SMPS in reverse. Instead of converting mains A.C. to D.C. voltage; the Class D circuit converts the D.C. power into a high power A.C. audio output.

The audio input is converted into a digital format; and is processed to control the switching of the D.C. power supply in very rapid pulses. A longer “on” pulse will result in a higher output voltage; and a shorter “on” pulse will result in a lower output voltage. The stream of pulses is then filtered to remove the high switching frequency, resulting in a smooth amplified output; without the need for big and heavy transformers!
