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 ).

In an audio amplifier, distortion may cause unpleasant tones to be superimposed on the true sound. There are many different configurations of audio amplifier circuitry, each with its own advantages and disadvantages. This particular circuit is …

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 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.

It helps a lot to first consider classes A, B and C as defined for a single transistor. Class A : full conduction during both alternances. Classe C : conduction during less than one alternace. Class B : conduction between one alternance, no more, no …

Audio Amplifiers from Class A, B, D to T. P. Marian. The final amplifier is the power source of every audio installation. Its job is to convert a small alternating voltage into a powerful signal for driving loudspeakers with as little distortion as possible. Delivering a large amount of power is not a simple task for an amplifier.
Class AB VS Class D Amplifiers || Which one is right for me?

By doing so, class AB amplifiers can keep a higher level of audio fidelity closer to class A amplifiers, while staying cooler and more efficient like a class B. Class D amplifiers take it a step further and they are even more efficient, and less hot, than their AB counterparts. The transistors in class D amps will quickly switch back and forth ...

"A class A/B amp is a class A amp while operating under these conditions; when the power spikes above that limit, it operates in class B mode. This transition happens seamlessly and continually." I guess it's a matter of semantics but in a proper Class A amplifier the output devices are biased halfway between saturation and cutoff (in the most ...
