Abstract
According to the requirements of ADS project for superconducting magnet power supply system,a controller with high stability for superconducting magnet power supply system is designed, and it mainly consists of optical ber module, digital to analog converter (DAC) and analog to digital converter (ADC) circuit. The DAC based on digitally controlled potentiometer (DCP) and eld rogrammable gate array (FPGA) can achieve high stability control of superconducting magnet power supply, and the value of current can be given by the DAC. The output stability of this DAC can be more than 2x105, which can fully meet the requirement of 5x105 for superconducting magnet power supply. The test data of the system is given, which veri ed the rationality and reliability of this design.
