Variable Dc Power Supply Schematic. This circuit is not an absolute novelty but it s simple reliable rugged and short proof featuring variable voltage up. A power supply can be given from the battery or from a hardware circuitry which converts the ac supply into the dc supply or step down ac to step up ac and vice versa.
Dc power supply 3a adjustable 1 2v 20v. A variable power supply is one which facilitates the user to vary and adjust the desired output voltage and output current. To 15 v 2a current using ic lm317.
This variable power supply is using 7805 7809 7812 or 7815 voltage regulators where the last 2 digits desktop pc linear power supply circuit p.
0 12v variable power supply at 3a. A transformer is used to step down the ac supply to 24v at 2a. 0 12v variable power supply at 3a. Hii friend today i am going to make variable voltage power supply using mosfet irfz44n in different circuit we require different voltages to operate the circuit so by using this circuit we can get desire voltages upto 15v let s get started.
