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.

High voltage regulated power supply schematic. 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 adjustable voltage regulator lm317 u1 offers short circuit. The universal power supply must operate from ac line voltage ranging from 90 to 264v 50hz or 60hz. Since the 5v secondary is not used a little more current than 120ma can safely be drawn from the high voltage secondary.

Build a regulated high voltage power supply for capacitor charging or another high voltage application. 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. You may like these lm338 5a variable regulator better life with high current in same voltage 1 25v to 30v. 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.

This instructable is for those with excellent electronic safety knowledge. For a transformer that can supply at least 30 amperes and voltage secondary coil should not be less than 18 volts. 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. The power transformer has three secondaries.
