Although you could use this design to deliver 20 amps with almost no modifications and with a proper transformer and a huge heat sink with a fan.

0 30v power supply circuit using lm317.

0 30v dc dual variable supply using lm317 lm337 max adjusts the voltage of 0 60v. In input out output adj adjust. Lm317 variable voltage regulator circuit lm117 lm217 lm317 variable voltage regulator characteristics. For experimenting electronic circuits and project we require variable power supply it requires center tap transformer.

Few useful circuits using the voltage regulator ic lm317 is shown here. 1 2v 20v 3v 6v 9v 12v high current for all circuit easy to use. Lm317 is a three terminal voltage regulator ic from national semiconductors. Hence ac voltage regulator circuits can be designed.

Lets make a high current power supply with lm317 voltage regulator which can supply upto 5 amp lm317 is one of the oldest most used and wonderful linear voltage regulators. Best adjustable dc power supply 3a. Some circuits based on lm317 voltage regulator. Input voltage can be up to 40v and output voltage can be adjusted from 1 2v to 37v.

How to use lm317 for producing a variable output. 0 28v 6 8a power supply circuit diagram using lm317 and 2n3055. How to make 3 3v 5v 12v and 24v regulated power supplies using the lm317 regulator. I personally love this ic yes it s not a transistor a lot not because it server it purpose well but because it s cheap easy and never disappoints you while making a regulated dc power supply.

The lm317 series of adjustable 3 terminal positive voltage regulators is capable of supplying in excess of 1 5a over a 1 2v to 37v output range. This is an easy to make power supply which has stable clean and regulator 0 28v 6 8 amp output voltage. This ic is normally available in to 220 package and. The lm317 is a 3 terminal positive voltage regulator with a 1 25 to 37 volts output voltage range.

It s high volt and starts voltage at zero. Lm317 power supply circuit diagram and calculations. By using two lm317 ic s you can regulate both the positive and negative swings of a sinusoidal ac input. The ic is capable of delivering up to 1a of output current.

Here we ll try to understand how to construct a simplest power supply circuit using the ic lm317. This design can produce a current of 20 amps with little modification use proper rating transformer and a huge heat sink with fan. Dual adjustable power supply circuit using lm317 and lm337. It s high volt and starts voltage at zero.

By using two 2n3055 transistors we become more then 2 times the amount of amps then the power supply delivers making it real though to brake.
