Classes of Power Amplifiers (Class A, B, AB, C, D ... Class D amplifier is the highest power efficient amplifier class in the A, B, AB, and C and D segment. It has smaller heat dissipation, so small heatsink is needed. The circuit requires various switching components like MOSFETs which has low on resistance. Class AB Amplifier Design and Class AB Biasing As we said above, the Class AB Amplifier is a combination of Classes A and B in that for small power outputs the amplifier operates as a class A amplifier but changes to a class B amplifier for larger current outputs. This action is achieved by pre biasing the two transistors in the amplifiers output stage. 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. 2000W Class AB Power Amplifier Schematic Design This is the circuit diagram of 2000W class AB power amplifier uses 7 pairs MJ15003 and MJ15004 transistors for the final amplification block.
