What is Ideal Transformer

Ideal Transformer

An ideal transformer in which no losses occur at all, in other words, the transformer Input is equal to the output of the transformer. As known by its name, its just theoretical as there must be some losses in real transformer.

Transformer input Power = Transformer Output Power.

PIN = POUT.

Also,

VIN = VOUT.

and,

IIN = IOUT.

In simple words, in ideal transformer, Input current is equal to output current as well as input voltage is equal to the output voltage, so the overall input power to the transformer is equal to the output transformer. Also, there is no leakage flux in ideal transformer windings.

But this imaginary and we does not have any ideal transformer in real electrical engineering world. but, in coming days, But, in coming days, there is a possibility due to using a superconductor (a conductor where no losses occurs). And we may use this module to explain and understand the real transformer design, working principle. etc and other related terms.

An ideal transformer is shown in the below figure. Current passing through the primary coil creates a magnetic field. The primary and secondary coils are wrapped around a core of very high magnetic permeability, such as iron, so that most of the magnetic flux passes through both the primary and secondary coils. If a load is connected to the secondary winding, the load current and voltage will be in the directions indicated, given the primary current and voltage in the directions indicated (each will be alternating current in practice).

  1. This is an amazing site for me.Because which i want to learn every thing is available here.
    It improves more if here i ask some questions which answer you can provided me through this site.
    So it can improves our knowledge about electrical technology.

  2. That’s a clever answer to a tricky quitseon

  3. very useful for all electrical engineers
