| Popis: |
A continuous operation with intermittent loading high voltage high frequency digital electric control generator is designed based on switching power supply technology and serial resonant inverter technology. Tube ARC suppressor is placed in order to limit arcing and a neural network PED control approach is established in order to improve the filament controller's properties. Tube stator current frequency spectrum is being used to estimate the X-ray tube motor's speed. Embedded real-time operating system-ARM7 is applied to the realization of the electric control generator. Simulation results testify that these methods are feasible and experiment results show that the X-ray power source satisfies the requirements of security inspection equipment. These methods have been widely used in the X-ray generator products. |
