Push pull amplifier schematic diagram

A Push — Pull amplifier is called that way, because it uses 2 groups of transistors and only one works at a time. One group pushes in one direction while the other pulls in another direction. Each group is responsible for amplifying a single phase of the input wave. See in the diagram. One group is yellow and the other is green. In this case there is only one transistor per group.

To get more information contact me at: webmaster audiodesignguide. After many years designing single ended amplifiers I have decided to start a series of test about the Push Pull amplifiers. These amplifiers are considered at a lower level than single ended but if you want a power enough to drive ESL loudspeakers and low distortion systems like Audiotechnology , Dynaudio , Scanspeak , Morel and Seas there is no other choice. The main problem of Push-pull amplifier is the not perfect distortion decay with the cancellation of even harmonics but if we keep the distortion level very low this consequence can be ignored and the sound will not be affected. Another characteristic of many Push-pull amplifier is the high global feedback used to get a good damping factor because to increase the output power often are used output transformers with low turn ratio.

What is a Push-pull Amplifier : Circuit Diagram and Its Working Principle


Push-Pull Amplifier is a power amplifier which is used to supply high power to the load. One transistor pushes the output on positive half cycle and other pulls on negative half cycle, this is why it is known as Push-Pull Amplifier. The advantage of Push-Pull amplifier is that there is no power dissipated in output transistor when signal is not present. Class A configuration is the most common power amplifier configuration. It consists of only one switching transistor which is set to remain ON always. It produces minimum distortion and maximum amplitude of output signal. The stages of the Class A amplifier allows same amount of load current to flow through it even when there is not input signal connected, therefore large heatsinks are needed for the output transistors.

A push pull amplifier is an amplifier which has an output stage that can drive a current in either direction through through the load. The output stage of a typical push pull amplifier consists of of two identical BJTs or MOSFETs one sourcing current through the load while the other one sinking the current from the load. Push pull amplifiers are superior over single ended amplifiers using a single transistor at the output for driving the load in terms of distortion and performance. A single ended amplifier, how well it may be designed will surely introduce some distortion due to the non linearity of its dynamic transfer characteristics.

So far, we have seen two types of class A power amplifiers. The main problems that should be dealt with are low power output and efficiency.

A Push-Pull transistor circuit is an electronic circuit that uses active devices connected in a particular way that alternatively supply current and absorb from connected load whenever needed. It used to supply high power to the load. A servo amplifiers is used widely because of a special trait that lets them transfer energy to load or even absorb power from the load at times. While the use of these components is extensive, the first choice when it comes to delivering power to these, is a push-pull transistor circuit. One transistor pushes the output on positive half cycle and other pulls on the negative half cycle, hence the name push-pull amplifier.

In our previous article, we have introduced you to amplifiers and its types. In our previous articles, we explained power amplifier , Amplifier classes , Class A power amplifier theory etc in detail. Here in this article, we are going to explore about Push-Pull Amplifier , its circuit, operation, advantages, and disadvantages in detail. A push-pull amplifier is a type of amplifier that can drive current in either direction through the load. In terms of distortion and performance, push-pull amplifiers are more efficient than single-ended amplifier because of its push-pull arrangement. In this arrangement, one transistor amplifies the positive half cycle whereas another transistor amplifies the negative half cycle of the signal i.

The Web This site. When a pair of similar transistors 2 x NPN or 2 x PNP are used in push-pull mode, it is necessary to supply their inputs with two identical anti-phase signals. This can be done by using a phase splitting transformer such as that shown in Fig. An output transformer with a centre tapped primary winding re-combines the two half cycles of the output waveform, so that the loudspeaker is fed with the complete waveform by the transformer secondary.
