X線装置用電力供給方法及び装置
Document Type and Number:
Japanese Patent JP4107626
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a total cost and to miniaturize a device white preventing noise and harmonics by supplying radioscopy power from a commercial AC power source during radioscopy operation of an X-ray apparatus, and supplying radiographing power from a storage battery to an X-ray tube during radiographing operation. SOLUTION: Operation power of a noise filter circuit 2, a rectifying circuit 3, a power-factor improvement circuit 4, and a charging circuit 5 is set in a rated radioscopy value or its double, for example in a 50 kW X-ray apparatus, in about 700 W, filament heating power is set in continuous 50 W or so in normal radioscopy, and since power for floating charge of a storage battery 7 even during radioscopy requires hundreds W, total power is set 1 kW. High voltage side power source circuit 11 and a filament heating circuit 14 are operated with commercial power source power during radioscopy, and floating charge of the storage battery 7 is conducted with surplus current. An inverter circuit 8 is operated in radiograph operation during radiographing, and most radiographing power is supplied from the storage battery 7. The noise filter circuit 2 having small capacity can be realized, and cost can easily be reduced.
