Transformers are used for impedance matching applications. This is explained with the help of the following figure:
The load impedance reflected on the primary side is redrawn as shown:
For the load to match with the source resistance:
Calculation:
With RL = 8 Ω, and RS = 200 Ω, the transformation ratio will be:
The turns ratio will be:
