Digital control system for the corrector power supply of the HLS storage ring
Stability of the corrector power supply is important for beam orbit stability of a synchrotron light source.In this paper
we report a digital control system for corrector power supply of the HLS storage ring
including the hardware
software and the measurement results.The hardware structure and work flow of the digital power supply controller is emphasized.The controller is composed of two cards of ADC and DSP.It adopts advanced DSP and FPGA as core.The controller communicates with IOC via optical fiber
and can easily change parameters of the power supply through the UART port.Operation of the storage ring with the digital control system for correcting the power supply indicates that the upgraded PS system meets the requirement of orbit stability.
