Transformer Applications – Definition
If we talk about the transformer applications in the electronics circuits then it is most common and widely used component with unavoidable features. Generally, the transformers are used to increase (Step-Up) and decrease (Step-Down) the AC voltages to operate electronic circuits. There are normally 5 types of applications for the purpose of transformer;
- Step-Up Transformer
- Step-Down Transformer
- Impedance Matching Transformer
- Isolation Transformer
- Coupling Transformer
