Abstract :
Accelerator applications need extremely precise power supplies (PS) for their various magnets. A fully digital control unit enabled identical control hardware for all the devices. In addition, it allowed a high flexibility for the control structures. Adaptations for the different PS are made simple by software. All the drift problems of previous analog solutions were reduced to the precision of one single analog to digital conversion. The achieved current stability and reproducibility is excellent
