Control system and control method of micro-focus X-ray source

The invention provides a control system and a control method of a micro-focus X-ray source, and belongs to the technical field of X-ray sources. The system comprises a control module, a tube core driving module, a voltage driving module and an X-ray tube, the control module is respectively connected with the tube core driving module and the voltage driving module, the voltage driving module provides voltage for the X-ray tube, and the tube core driving module receives an instruction of the control module and outputs cathode level, grid level and filament voltage to the X-ray tube. The method is implemented in the control system, accurate control over the voltage and the current of the X-ray tube is achieved, it is guaranteed that the voltage and the current of the X-ray tube are stable and reliable, the consistency of the actual output value and the preset value of the X-ray tube is guaranteed, and the working stability of the micro-focus X-ray source is greatly improved. 本发明提供了一种微焦点X射线源的控制系统及控制方法，属于X射线源技术领域。
