For smaller voltages we normally use batteries as a reliable source. Generally to convert line frequency ac to dc a line frequency diode bridge rectifier is used. You can adapt it to your own requirements as explained in the.
The power supply designed in this project is an adjustable linear regulated type so the output voltage of the circuit is constant and is varied mechanically with the help of a variable resistor. As shown in schematics the variable voltage of 15 to 24V is mapped to 0-45V by using potential divider circuit since our Arduino can only read voltages from 0-5. A Variable DC Power Supply is one of the most useful tools on the electronics hobbyists workbench.
A variable dc power supply is one of the most useful tools on the electronics hobbyists workbench. A variable dc power supply is one of the most useful tools on the electronics hobbyists workbench. A Variable DC Power Supply is one of the most useful tools on the electronics hobbyists workbench.
Normally the IC 7805 is considered as a fixed 5 V voltage regulator device. In our previous tutorial we built a 12V and -12V Dual Power Supply Circuit and a 5V and -5V Dual Power Supply Circuit but the outputs from these circuits are fixed so in this tutorial we are going to design a variable dual DC power supply circuit which can provide variable output voltage ranging from 14V to -14V. 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.

This circuit is not an absolute novelty but its simple reliable rugged and short-proof featuring variable voltage up to 24V and variable current limiting up to 2A. You can adapt it to your own requirements as explained in the notes below.
It is used as an interface between utility and most of the power electronic equipments. Posted in Variable Supply Power supply Basic Electronics LM338 Datasheet Adjustable Power Supply 5A and 10A If you want to a LM338 variable dc voltage power supply circuit during 12V to 30Vdc and can provide a current maximum to 5A. The complete circuit of this Variable Power Supply is shown below Follow the Schematics and solder you components accordingly.
In this project an adjustable power supply circuit is designed which inputs AC mains and provides 0 to 30V 2A DC Voltage as output. Variable Power Supply with Digital Control. And we are introducing a very common regulator IC called lm317 this particular ICs are used to build variable power supply circuits and fixed power supply circuits today we try to build a variable power supply circuit.
Well suited to supply the circuits shown in this website. However with a basic workaround the IC could be turned into a 5 V to 9 V variable regulator circuit as shown above. Instead of using batteries which have a limited lifetime a variable DC power supply can be used which is implemented in this project.
This circuit is not an absolute novelty but its simple reliable rugged and short-proof featuring variable voltage up. Simple power supply circuit provides variable output voltage 12V to 15V DC and load current up to 3 Amps onboard trimmer pot provided to adjust the output voltage. More Power MOSFET Bridge Rectifier.
