Problems solved by technology

Of course, there are many ways to use batteries to make up for the shortage in the market at present, but using batteries as energy storage components is either too bulky or too expensive, and high-current discharge will cause great damage to the battery, which seriously affects the use of the battery. Lifespan, usually about two years will need to be replaced
And the charging time of the battery is longer, and it is inconvenient to use, etc., which limit the development of this technology.

Embodiment Construction

[0008] The network power is divided into two circuits, one is connected to the charger 2 to charge the supercapacitor group 1 to provide energy for the main inverter power supply, and the other group is directly connected to the rectified rectifier filter circuit 3 to provide energy for the main inverter power supply, through the control circuit 5 And switching circuit 4 selects one road power supply in above-mentioned two-way power supply (seeing figure 1 ). When the X-ray machine performs small-dose exposure or fluoroscopy, the rectifier filter circuit 3 is selected to supply power to the main inverter power supply; when the X-ray machine is exposed to a large amount of exposure, that is, spotting or filming, the supercapacitor group is selected to supply power to the main inverter power supply.

[0009] The supercapacitor bank consists of 180 supercapacitors in series, with a maximum voltage of 480V and a maximum discharge current of 200A. The charger equipped for the supe...

Abstract

The invention relates to a supercapacitor-based X-ray machine power supply device, belonging to the technical field of medical apparatuses. The supercapacitor-based X-ray machine power supply device is characterized in that a grid is divided into two paths, one path is connected with a charger 2 to charge a supercapacitor group 1 and provide power for a main inverter power supply, the other path is directly connected with a rectification filter circuit 3 to supply power for the main inverter power supply, and one of the two paths is selected by a control circuit 5 and a switch circuit 4 to supply power. When an X-ray machine exposes point sheet or shoots sheets in the large amount, the supercapacitor group is selected to supply power for the main inverter power supply. The supercapacitor-based X-ray machine power supply device disclosed by the invention has the advantages of simple and reliable control method, convenience for operating, high efficiency, low production hardness and low cost.

Description

technical field [0001] The invention relates to an X-ray machine power supply device using a supercapacitor as an energy storage element, which is mainly used in the field of medical X-ray imaging, especially for a relatively high-power model with 220V network power input. Background technique [0002] Since the beginning of the 21st century, medical imaging technology has shown a rapid development trend. Industrial frequency machines have basically been eliminated and replaced by high frequency machines. In order to obtain better imaging effects, people increase the power of X-ray machines. As we all know, high-frequency X-ray machines require a stable and reliable DC power supply. If the network power is used for direct rectification, the requirements for the network power are more stringent. For those areas that use small hydropower generation, and those places with large power equipment around, such as: township hospitals, mine hospitals, etc., the power supply status ...
