Stable power supply for high voltage power supply for the core of a high voltage of the PWM – Controller TL494, loaded with over 4050 followers on a pair of powerful field-effect transistors, switching the primary winding of step-up transformer (4 + 4 turns – the primary winding, 200 turns – the secondary winding). With the secondary winding through a rectifier with voltage doubling and smoothing filter RC LC voltage reaches the voltage divider, and the regulator output voltage. Scheme can be used as a voltage converter to power the photomultiplier.
