High Voltage Regulated Power Supply Schematic

This project can cost less than 15 and you will be able to obtain upwards of 1000v and be able to adjust the output from 0 1000v.

High voltage regulated power supply schematic.

In the circuit you can see the t1 is a mains transformer with a ratio of 1 1 for. You may like these lm338 5a variable regulator better life with high current in same voltage 1 25v to 30v. The universal power supply must operate from ac line voltage ranging from 90 to 264v 50hz or 60hz. Build a regulated high voltage power supply for capacitor charging or another high voltage application.

High power dc regulator 4 20 volts 20 amps by lm338. 720v at 120ma center tapped for the plate and screen supplies 6 3v at 3 5a for the tube filament and bias power supply and 5v at 3a not used. Since the 5v secondary is not used a little more current than 120ma can safely be drawn from the high voltage secondary. The power transformer has three secondaries.

The above universal power supply circuit provides a variable voltage between 3 to 30v the maximum current of 1 5a and addition of modules can provide a higher current. 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. For a transformer that can supply at least 30 amperes and voltage secondary coil should not be less than 18 volts. 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.

This instructable is for those with excellent electronic safety knowledge.
