The requirements of current output accuracy and long-term stability are very high in bipolar magnet power supply for Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou. According to the requirement of actual index, a DAC board is designed with high precision and high stability for power supply. Due to the design requirements for ultra-high precision and stability, the output accuracy and long-term stability of the analog given circuit design and device selection were emphasized, through experimental data testing on the actual power supply. The experimental results showed that the design requirements were met.

摘要

The requirements of current output accuracy and long-term stability are very high in bipolar magnet power supply for Cooler Storage Ring of Heavy Ion Research Facility in Lanzhou. According to the requirement of actual index, a DAC board is designed with high precision and high stability for power supply. Due to the design requirements for ultra-high precision and stability, the output accuracy and long-term stability of the analog given circuit design and device selection were emphasized, through experimental data testing on the actual power supply. The experimental results showed that the design requirements were met.
