Abstract
Purpose
This power supply prototype is developed for the quadrupole magnets in the storage ring of HEPS. The project requires a high current stability of these power supplies, in order to master the key technology of this type of power supply in advance, a prototype is made in the project of HEPS test facility.
Methods
Modularization is used in the prototype’s topology and a combination of digital and analog control is adopted in the closed-loop control. Three control loops are used to improve the output current’s quality. In order to improve the current stability, the key devices in the circuit are under thermostatical controlled.
Results
The acceptance test results for the NDRC are given in details, which show that all the parameters are better than the design indexes.
Conclusions
After a lot of experiments and tests, all the parameters of this prototype passed the acceptance test. Among the results, the stability of this prototype achieved 5.2 ppm, the repeatability is 3.2 ppm, and the low-frequency voltage ripples are lower than the requirements of Physicists. The success of this prototype means that the requirements of power supplies in physical design can be met.
