The power supply of intermediate frequency wh ose output frequency is 400Hz can provide power for the system of motion, navigation an d weapon equipments. The wave output from traditional pow er supply of intermediate frequ ency is unsteady. The design in this text adopt the oscillati ng circuit based on quartz crys tal oscillator, and the hardware made up of the divided frequency circuit, integral circuit, amp lifying circuit, demodulation circuit and SCM (Single Chip puter )system can control the output voltage at the end. The circuit realizes the s teady output of voltage, and the characteristics such as small
