Ideal Transformer With No Load
In this type of ideal transformer there is no load connected to the secondary part of the transformer hence, no current flows through this part. As there is no current in the secondary part, no voltage is induced in the primary part. The current that flows through the primary part is the magnetizing current that is required to establish the magnetic field in the core of the transformer. The primary current is due to the applied voltage and the inductance of the primary coil.
An input voltage [Tex]V_1[/Tex] is given to the primary winding of the transformer because of which a small magnetizing current [Tex]I_m[/Tex] flows through the primary winding. This current produces a flux which induces [Tex]E_1\: \: and \:\: E_2[/Tex] in primary and secondary respectively.
As the current in the secondary winding is zero, there is only magnetizing current which lags 900 of the input voltage V1. The induced EMFs E1 and E2 are inversely proportional to the input voltage.
What is an Ideal Transformer?
In this article, we will look into a special type of transformer known as the Ideal Transformer which is designed in ideal condition with no loss and 100% efficiency. We will discuss what is a transformer, ideal transformer. We will look into the working principle, properties, and equations of the ideal transformer. We will also look into an ideal transformer with load and with no load. In addition to these, we will also see the phasor diagram. Later, we will discuss the advantages, disadvantages, and applications of, the ideal transformer.
