In the field of modern medical technology, a mobile CT (computed tomography) apparatus capable of being used in a radiology department is being gradually applied to medical environments such as an operating room, an icu, and a field emergency. Compared with conventional CT, mobile CT has small volume, light weight, mobility and low environmental requirements, and can be used in situations where the patient is not conveniently mobile or where an emergency event requires CT scanning.
In the working process of CT, the electric energy needed by the bulb tube at the moment of exposure is extremely large. In the traditional CT machine, the high voltage is directly obtained from the CT frame by adopting the conductive slip ring technology, but the three-phase 380V industrial power supply is required to be used in the method, the use requirement of the power supply is required to be reduced for field emergency treatment and the like due to the application environment of the mobile CT, the CT machine is suitable for providing stable power supply for the normal work of the CT under the condition that the power supply is not stable enough, and the traditional CT cannot realize the CT.
