A 12VDC power supply is a device that supplies electrical energy to a low voltage DC load. The AC power is converted to DC using simple circuits which gives an invariable and absolutely controlled DC power at the output. Thus, the primary purpose of a power supply is to convert electric current from the source into the required voltage, frequency, and current, which powers the load. A simple regulated power supply circuit mainly consists of an ordinary power supply with a device that regulates the output voltage according to the requirement. Here we will build a circuit with an output voltage range of up to 12V and current output of up to 3A which can be utilized in applications where the output current requirement is up to 3A.
