Abstract

Abstract

The paper describes the design of CRDM digital current adjustment equipment which is based on the transfer phase trigger theory. The current adjustment equipment is ameliorated through PID close loop control, the real time monitoring of time sequence current. For meeting the requirement of DAS, the current rack-off function is designed. The test result shows that the equipment meets the operation requirement of CRDM, and some technical points are optimized.
