How dc supply is given to transformer used in push pull amplifiers?
Wiki User
∙ 9y ago
The dc is supplied via a centre-tap on the transformer. This ensures zero dc net flux in the transformer core, which enables a much smaller core to be used.

Why the name push pull is given to class B power amplifier?
Because two amplifiers are used to accomplish class B power amplifier. One is used to push the current and the other one is used to pull the current. These two amplifiers are almost same but one is connector supplied and the other one is emitter supplied.
What is the ampere range value of transformer?
This typically has to do with how many amps you can safely pull from the secondary of the transformer.
What is the difference between Ohm and Ohm CT in impedance of an audio transformer?
The side of the transformer that has the ohm CT which translates into a winding on the transformer that has a center tap . This side of the transformer was likely attached directly to the audio output transistors set up in push pull configuration. This is what the center tap is for. This side of the transformer would have a higher impedance and is directly driven by the power supply to provide amplification The transformer also isolates the amplifier voltage from the other side which is of low impedance. This may be in the range of 8 to to 16 ohms which would be directly tied to a speaker.
How is transformer saturation avoided in class B push pull amplifier operation?
In class B amplifier no DC biasing required, thus lack of of DC current in inpunt and load, saturation of core avoided
What is a straight pull tensile test?
A tensile test machine is designed to give a straight line pull on a member so that it measures only direct tensile stress given as the force applied divided by the member area

How many amps does a 600 watt low voltage transformer box pull?
The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.
How to Construct a single to threephase inverter?
Very complicated, first you have to rectify your single phase to get DC then you need a 3 phase sine wave signal, that can be generated with a MCU, to drive three pairs of push pull amplifiers that is connected to a three phase transformer's primary windings and you have your output at the secondary
What is an explanation of the cooling of transformer?
a transformer can be cooled by using forced air-essencially attaching fans to help pull heat away.

Does the volume go to "11" on any car amplifiers?
No. Police can pull you over for noise pollution so they tend not to make them do higher.

Does a 600 watt garden lights transformer pull 600 watts all the time or just the load from the lights you have on it?
Watts are power. If the lights were mostly or totally switched off, you'd have a circuit generating 600W of heat somewhere if the transformer still took 600W, not only that, but when you switched on, the 600W that the transformer was consuming, would not disappear, so the total drain would be 1.2kW. ---- Don't understand the above answer. The 600 watts on the transformer nameplate is the maximum amount of wattage that the transformer can produce and still be within its safety limits. It doesn't draw that wattage all the time. If you had two 50 watt lamps connected to the transformer then the transformer has the capacity of 500 watts left. The transformer will only produce the wattage that the load requests. The transformer has the ability to supply twelve 50 watt bulbs. 12 x 50 = 600. Any more bulbs than 12 and the transformer is in an overload condition.
Why Mrcovey given Douglass a undbroken oxen to pull the cart?
It is not clear from the given information why Mrcovey gave Douglass an unbroken oxen to pull the cart. Additional context or details are needed to provide a more accurate answer.
What is the responsible for inflation according to the demand-pull theory?
According demand-pull theory, what causes inflation is a strong demand and a lower supply. By having a greater demand, people pull prices up. Economists will often say that demand-pull inflation is a result of too many dollars chasing too few goods.
what are the causes of running inflation?
Demand Pull Inflation , where demand increased from supply
