Here we designed a power amplifier circuit using push pull class AB configuration to derive a power of 150W to drive a load of 8 Ohms speaker. Therefore in class AB amplifier design each of the push-pull transistors is conducting for slightly more than the half cycle of conduction in class B but much less than the full cycle of conduction of class A. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards. The Class B topology eliminates the dc bias current and dissipates significantly less power. Single ended designs tend to require special attention to the power supply to mitigate this issue.
