The high voltage power supply consists of an oscillator, step-up transformer, voltage multiplier and feedback loop for stabilizing the output. The oscillator is spilt into IC timers suitable for astable and monostable mode using with high frequency that leads to ferrite core small X-former. This type of HVPS can be used in the nuclear field for very low current biasing semiconductor detectors and gas-field detectors to higher currents working with photo multiplier tubes.
