This particular circuit is called a “class B,” push-pull circuit. Most audio “ power ” amplifiers use a class B configuration, where one transistor provides power to the load during one-half of the waveform cycle (it pushes) and a second transistor provides power to the load for the other half of the cycle (it pulls ).

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. The emitters are shorted and the collectors are given the V CC supply through the primary of the output transformer T r2. The circuit arrangement of class B push-pull amplifier, is same as …

Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for one half cycle of the input signal. Since the active device is switched off for half the input cycle, the active device dissipates less power and hence the efficiency is improved.

Class B amplifier is a type of power amplifier where the active device (transistor) conducts only for one half cycle of the input signal. That means the conduction angle is 180° for a Class B amplifier. Since the active device is switched off for half the input cycle, the active device dissipates less power and hence the efficiency is improved.

As for proper operation of this amplifier a Class B output stage op-amp is required, the original circuit was modified accordingly. Using a mains transformer with a secondary winding rated at the common value of 25 + 25V (or 24 + 24V) and 100/120VA power, two amplifiers can be driven at 45W and 69W output power into 8 and 4 Ohms respectively, with very low distortion …

Class B Amplifier . The Class B amplifier is a bit different from the Class A. It is created using two active devices which conduct half of the actual cycle, ie 180 degrees of the cycle. Two devices provide combined current drive for the load. In the above image, an Ideal Class B amplifier configuration has been shown.

The Class B amplifier is as basic as they come, yet still has a nice and warm sound to it. It is consists of two separate stages, the first one is responsible for the voltage gain of amp and to set a correct voltage offset for output. The second part of the circuit uses power transistors to boost the current the amplifier can supply the load with.

Class B amplifiers use a push-pull amplifier topology. The output of a Class B amp incorporates a positive and negative transistor. To replicate the input, each transistor only conducts during half (180°) of the signal waveform ( Figure 2 ). This allows the amp to idle with zero current, thereby increasing efficiency compared to a Class A amp.
