High Current Variable Voltage Regulator Circuit Diagram

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.

High current variable voltage regulator circuit diagram.

None other than a voltage follower with high current capability. 10 ampere adjustable voltage regulator using msk5012. Also the important is the overload protection. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection.

This regulator is 0 50v variable power supply circuit. This is an easy to make dc to dc voltage regulator circuit using the reliable msk5012 ic. Circuit diagram lm317 voltage regulator ic. The output current is 10 a of this circuit.

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. In the circuit you can see the t1 is a mains transformer with a ratio of 1 1 for. The output voltage can be programmed using the two resistors r1 and r2. 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.

Power follower circuit got confused what it is. You may like these lm338 5a variable regulator better life with high current in same voltage 1 25v to 30v. 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. Which you can adjust output voltage in a wide range between 0v to 50v and a current at least 3a.

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. Since it will immediately cut off when a load short circuit. For a transformer that can supply at least 30 amperes and voltage secondary coil should not be less than 18 volts. It s an adjustable three terminal voltage regulator ic with a high output current value of 1 5a.

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.
