Abstract: Using Max1847 as the core chip, a kind of flyback switching high voltage power supply was designed for nuclear instrumentation according to the design requirements of nuclear radiation measurements. The working principle of flyback switching power supply topology was analyzed. It also presented that the main circuit design of high voltage power supply, the design specifications of the various components, the key parameters of the flyback transformer, the main parameters of the high voltage power supply, as well as the analysis of the experimental results. According to the test result and practical application, Max1847 is suitable for the nuclear instrumentation's high voltage power supply system design.

Keywords: nuclear instrumentation; high voltage power supply; power supply topology; flyback switching power supply; PWM
