A power supply whether it is a battery or a switched mode ac adapter is one of the most important tools in electronics.
0 12v variable power supply.
A linear power supply continuously converts the ac to dc with a constant.
In the circuit with the components value makes the output voltage range of approximately 1 25 to 13 5 volts.
This is a 0 12v variable power supply circuit at 3 amp.
In contrast to a linear power supply the transistor switches continuously between dissipation states to vary the ratio of on and off times.

Obviously you need something to supply electricity to your electronic projects.
A switched mode variable power supply is an electronic power supply that utilizes a switching regulator to convert electrical power.
We often require dc voltages for our experiments then why spend money on cells or rechargeable batteries why not build a power supply that takes ac 220vrms and gives required output.
Making your own power supply is also one of th.
Introduction the purpose of this instructable is to make a power supply that can give output of 5v constant and 0 12v variable output.
