High-voltage Regulated Power Supply

High-voltage Regulated Power Supply

The basis of high-voltage regulated power source is pulse-width modulator comptroller TL494, loaded through follower 4050 on the pair of the powerful field-effect transistors which commutate the primary winding of step-up transformer (4 + 4 coils – primary winding, 200 coils - the secondary winding). High voltage gets on the voltage divider, and on the regulator of output voltage from the secondary winding through a rectifier with doubling of voltage and ripple filter RCLC. A circuit can be used as a transformer of voltage for the supply of photomultiplier tube.
