Title: Inverter controlled x-ray high voltage generator
Inventor: HATAKEYAMA KEISHIN
IPC: H05G1/32
Filed: 1991-12-10
Abstract: PURPOSE:To miniaturize a generator by boosting the extent of supply voltage twice as large with a three-phase AC supply voltage rectifier circuit. CONSTITUTION:Three-phase 200V AC voltage is rectified to the extent of double voltage by a specified rectifier circuit 26, and converted into a DC voltage of about 400V. This voltage is smoothed by a reactor 9 and a capacity 10 and fed to an inverter circuit 27. A voltage control circuit 24 determines the operating frequency of an inverter corresponding to a voltage conversion rate at the inverter circuit 27 from a relationship between pressure rise ratio of a high voltage transformer 20 and setting tube voltage, controlling a transistor in the inverter circuit 27 via a base drive circuit 25. The inverter circuit 27 and the transformer 20 are resonated together, and thereby a high frequency voltage is produced at the secondary side. This voltage is converted into DC by a rectifier circuit 21, and smoothed by a high tension cable, thus it is impressed on an X-ray tube 23 as tube voltage.
