Design and Development of Low-Cost, Highly Stable Regulated High-Voltage Power Supply for Radiation Detector

摘要

In this paper we design and develop a highly stable and low cost regulated DC power supply for Geiger Müller (GM) Counter/detector. A regulated high voltage power supply is an important power source to bias gas-discharge tubes, X-ray tubes, and radiation detectors etc. A highly stabilized regulated 575 volts DC power supply was developed using the pulse width modulation (PWM) control technique from a 5 volt supply. It is specially designed for biasing GM detector for the area radiation monitor. The output high voltage can be adjusted at any suitable value by adjusting the preset potentiometer.
