Research on Accelerator Power Supply Digital Controller Based on Transceiver

    摘要
  • 摘要: 为满足强流重离子加速装置（HIAF）对电源控制器多版本兼容和高精度控制性能的要求，研发了1套基于串行收发器的加速器电源数字控制器（APSDC）。该控制器采用基于总线互联的模块化设计架构，在保证加速器电源数字控制器高精度控制性能的前提下，兼具多版本兼容能力。设计了1套基于串行收发器的高速同步数据总线（HSB）用于数字控制器子板间数据通信，总线带宽达2 Gbps，且板间数据同步误差低于1 ns。电源上线运行实验结果表明，APSDC各项设计指标符合HIAF对电源的高精度控制及其他关键性能的技术要求，并具备较强的系统扩展性。

     

    Abstract: 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.
