Best Answer

A step-up transformer increases (or "steps up") the voltage of an alternating electrical current. For example, a step-up transformer could be used to increase 120V AC to 277V AC to provide power to 277V electrical equipment in a building that does not already have a 277V electrical system.

Other examples where a step-up transformer might be used include these:

  • Using 240V AC equipment with a 120V AC mains supply.
  • Generating high voltage for use with tubes, such as a CRT.
  • Generating high voltage for use in electric energy distribution.

What is the name of a step-up which increases the voltage of electric energy that is generated at a power?

An electrical transformer can step up (or step down) the voltage.


Convert a US to UK voltage?

If you mean in domestic use, the US is at 120 V and the UK at 240 V. So you need a transformer with a 2 to 1 turn ratio, to step up if using a UK appliance in the US, or to step down if using a US appliance in the UK.


Step down transformer of a specs of 110 primary to 24 v 12va CAn you used a 110v primary to 24v 20 va What is the difference between them?

Yes. The Va numbers indicate the rating of the transformer (12VA indicates that you can draw upto 12/24 = 1/2 Amps at 24 volts and 20VA indicates that you can draw about 20/24 = 0.83 Amps). Usually 20va transformer will cost more than the 12va transformer. So, unless a higher power output is required, it is adequate to use the lower rating transformer. However, you cannot go the other way - if you use a 12va transformer in-lieu of the 20va one, if the application needs more power, then you have a reliability problem. The transformer will have more loss, heat-up and then eventually burn out.


What device raises voltage?

Depending on your application... Use a voltage dividor (two resistors) if it doesn't draw a lot of current. You could also try a voltage regulator or using an op amp as a buffer, with the input the voltage you want. That voltage could come from a voltage divider, since op amps draw extremely low current.


What is a Step Down Transformer do?

High alternating voltage will be reduced to low alternating one. Such step down transformers are used in power adaptors for electronic devices such as video games etc

What is the use of step up and step down transformer?

step up transformer is to icrease the voltage but keeping the frequency same. step down is use to get less voltage than input given but of same frequency. Generally step down is use,we reqiure it in oor house(in mobile charger etc.).It is also use in rectifires.


Does a basic transfomer in its normal operation use step up voltage step down voltage step up current or all?

A transformer has a primary and a secondary side. There is a ratio of windings from one side to the other that dictates whether it is a step up or step down transformer. The transformer is usually marked as to the input and output specifications. The current is directly proportional to voltage. If you had a transformer that was a step up from primary to secondary, it would be step down from secondary to primary.


Can you use a step down transformer as a step up transformer by reversing the secondary voltage as a primary voltage?

Yes a Tesla coil or ignition coil is an example.
