The Simulation Of Suppressor Power Supply In DNB System And The Design Of TiMer

Suppressor power supply is the key of DNB system, the requirements of its 9 power supplies are rigorous. This power supply also protects the system , if any fault happens this power supply will cut off the supplies of DNB system.In the paper the structure of DNB was introduced, and the theory of negative high voltage power supply was stressed. A new model of vacuum tube was described in the paper, using this model some simulation was made. The results of the simulation proved that this model was feasible, and it can provide guidance of the trial of the DNB system.The design of the timer in DNB system was also described, its successful trial established a good foundation for the running of DNB system.
