针对加速器驱动次临界系统(ADS)注入器Ⅱ对超导磁铁电源系统的要求,设计了一款主要由光纤模块、数模转换器(DAC)和模数转换器(ADC)相关电路组成的高稳定度的超导磁铁电源控制器。提出了一种基于数字电位器(DCP)与现场可编程门阵列(FPGA)所组成的DAC,该DAC可以实现高稳定度的超导磁铁电源的控制,电源电流值通过该DAC给定,其电压给定输出稳定度优于2×10-5,完全满足超导磁铁电源系统5×10-5量级的稳定度要求。最后给出了系统的实际测试数据,验证了设计的合理性和使用的可靠性。
Aimed at the requirements of superconducting magnet power supply system for Accelerator-Driven Sub-critical System (ADS) injector II, a high-power, high-power, high-power system consisting of fiber optic modules, DACs and ADCs was designed. Stability of the superconducting magnet power controller. A DAC based on Digital Potentiometer (DCP) and Field Programmable Gate Array (FPGA) is proposed to control the high-stability superconducting magnet power supply. The value of the power supply current is given by the DAC. The Voltage given output stability better than 2 × 10-5, fully meet the superconducting magnet power supply system 5 × 10-5 magnitude of the stability requirements. Finally, the actual test data of the system is given to verify the rationality of the design and the reliability of the use.
