Research on Accelerator Power Supply Digital Controller Based on Transceiver

To meet the requirement of multi-version compatibility and high-precision control of the power supply controller in High Intensity Heavy Ion Accelerator Facility (HIAF), an accelerator power supply digital controller (APSDC) based on transceiver was developed. The controller was based on the functional modular and system bus architecture. It has the compatibility, extensibility of multi-version and high-precision control performance of the accelerator power supply digital controller. A high-speed synchronous bus (HSB) based on transceiver was deployed inside the controller. Its bandwidth achieves 2 Gbps and its synchronization error is lower than 1 ns. The on-line running test result shows that all APSDC design indicators meet the technical requirement of HIAF for high-precision power supply control and other key performances, and it has strong system scalability.
