Circuit diagram :
Components and its function: :
1. Transformer- An electrical device which transfers electrical energy from one electric circuit to other, without changing the frequency. The energy transfer takes place with change in voltage and current.
2. Rectifier- Convert AC into pulsating DC.
3. Inductor- Blocks AC components of rectified output and only pass DC components.
4. Capacitor- It bypasses AC components if any and gives DC to load.
