Description

technical field [0001] The invention relates to the field of medical devices, in particular to a filament current control method and device. Background technique [0002] The tube current of the X-ray tube determines the amount of X-ray radiation, which has a decisive impact on the quality of diagnosis and treatment. In the X-ray tube, the tube current is formed by the electrons excited by the heating of the filament under the action of a high-voltage electric field. The magnitude of the tube current is affected by the temperature of the filament, and the temperature of the filament depends on the magnitude of the filament current. That is to say, the magnitude of the filament current affects the X-ray radiation of the X-ray tube, and therefore, the control of the filament current becomes particularly important. [0003] figure 1 For the prior art, the filament power supply circuit topology, such as figure 1 As shown, when the filament current is controlled by the filame...
