Class B Push Pull Power Amplifier Circuit Diagram. Circuit diagram for class b amplifier is given below. At this moment q2 remains in off state.
The emitters are shorted and the collectors are given the v cc supply through the primary of the output transformer t r2. The circuit of a push pull class b power amplifier consists of two identical transistors t 1 and t 2 whose bases are connected to the secondary of the center tapped input transformer t r1. Figure shows a diagram for push pull operation an ac input signal is applied to the push pull circuit with each half operating on alternate half cycles the load then receiving a signal for the full ac cycle the power transistors used in the push pull circuit are capable of delivering the desired power to the load and the class b operation of.
The emitters are shorted and the collectors are given the v cc supply through the primary of the output transformer t r2.
When the input signal is positive q1 starts conducting and produce a replica of the positive input at the output. At this moment q2 remains in off state. Circuit diagram for class b amplifier is given below. The circuit diagram for a push pull amplifier consists of two transistors q1 and q2 which are npn and pnp respectively.
