Ideal Transformer With Load
Ideal transformer with load is a type of transformer where a load is connected to secondary winding of the ideal transformer. When current flows through the secondary section a magnetic field is created around it, by the principle of electromagnetic induction the changing magnetic field induces a voltage in the primary part of the transformer. The ratio of number of turns in the primary to the number of turns in the secondary part will determine the ratio of voltage in the primary and secondary part.
Let’s consider a load of [Tex]Z_L[/Tex] is connected to the secondary part of the transformer. This will induce an EMF E2 along with current I2.
So, we can write, [Tex]I_2=\frac{E_2}{Z_L}=\frac{V_2}{Z_L}[/Tex].
([Tex]E_2=V_2[/Tex] in case of ideal transformer)
I2 current flowing in the secondary part creates a magnetomotive force. This force produces a flux which is in the opposite direction of the main flux. This flux will make some changes in the core flux. to counterbalance the flux the primary current should be,
[Tex]N_1I_1=N_2I_2 \newline \Rightarrow I_1=\frac{N_2}{N_1}*I_2[/Tex]
The phasor diagram of the ideal transformer with load is given below where, the current I2 will lag behind the EMF E2 because we assumed the load to be inductive. The lagging angle will be [Tex]\phi_2[/Tex] . Also, we will not consider the load current as the transformer is in ideal condition.
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.
