Power amplifier classes
Power amplifier classes. Power amplifier circuits (output stages) are classified as A, B, AB and C for analog designs—and class D and E for switching designs. The classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current. The image of the conduction angle derives from amplifying a sinusoidal signal.Trevor Marshall Class D Audio Amplifier Design TDA7498 ...
Here is the output voltage seen in a typical Class D amplifier with a slightly underdamped output filter. You can see the PWM 3usec signal (330KHz) superimposed on the lower frequency square wave, and you can see the overshoot (at about 25KHz) which has resulted from the underdamped filter, resonant in the mid 20s KHz.Angular
