High Current Variable Voltage Regulator Circuit Diagram

In the circuit you can see the t1 is a mains transformer with a ratio of 1 1 for.

High current variable voltage regulator circuit diagram.

None other than a voltage follower with high current capability. It s an adjustable three terminal voltage regulator ic with a high output current value of 1 5a. Power follower circuit got confused what it is. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection.

The circuit shown above from the edn article high current supply uses standard three terminal regulator has two lm7812 voltage regulators connected in parallel for a maximum total output current of 2 amps double the rated current of one lm7812. This regulator is 0 50v variable power supply circuit. You may like these lm338 5a variable regulator better life with high current in same voltage 1 25v to 30v. Since it will immediately cut off when a load short circuit.

Which you can adjust output voltage in a wide range between 0v to 50v and a current at least 3a. The lt1038 is a three terminal adjustable voltage regulator which is capable of providing of 10a output high current at 1 2v to 32v range. Here is the variable high voltage dc power supply circuit which we can customize the output voltage from 0 to 311vdc and it is protected the current over the limit that we define at about 100 ma. From all principles above we have circuits applications as shown in figure 4 if you want to add the ic lm338 enabling them to be higher current.

Diodes d1 d2 and d should be 1n4007 according to the edn article but common 1n4001 diodes will be fine as they are rated up to 50v which is. Here you will find how an ordinary lm317 circuit could be converted into a high current 20 amp variable power supply circuit using just a few 2n3055 power transistors in conjunction with a standard lm317 voltage regulator circuit stage. For a transformer that can supply at least 30 amperes and voltage secondary coil should not be less than 18 volts. This is an easy to make dc to dc voltage regulator circuit using the reliable msk5012 ic.

The output voltage can be programmed using the two resistors r1 and r2. High power dc regulator 4 20 volts 20 amps by lm338. The output current is 10 a of this circuit. Circuit diagram lm317 voltage regulator ic.

1 25 v to 32 v 10 a voltage adjustable regulator circuit by this regulator circuit output load can be connected up to 10 a load.
