| Abstract: | The accelerator power supply is protected by detecting the di/dt and d u/d t, when the power supply is arcing. The protection characteristics of the DNB power supply system are studied. Based on this, the detection circuit of di/dt and du/dt in the power supply arcing and the corresponding protection circuit are designed.Therefore the protection of the accelerator power supply can be achieved in advance. |

| Keywords: | Diagnostic neutral beam Accelerator power supply Detection of d i/d t and d u/d t Protection of arcing |
