Hybrid type X-ray generator for fluoroscopy X-ray system available in low-capacity AC power source

Fluoroscopy X-ray system uses a 32[kW] or greater X-ray generator for obtaining real-time moving images and high-resolution images. Conventional X-ray generator for fluoroscopy X-ray system needs a high-capacity AC power source more than 40[kVA] to perform both long-time low-power fluoroscopy and short-time highpower spot exposure. In this paper, we propose a hybrid type X-ray generator for fluoroscopy X-ray system which can perform fluoroscopy and spot exposure with a low-capacity AC power source and EDLC as an energy storage device. Proposed X-ray generator has power conversion circuits such as hybrid power input circuit, high voltage power supply, filament driver, and rotor driver. A 32[kW] class hybrid type X-ray generator with EDLC as an energy storage device for fluoroscopy X-ray system was constructed, and its validity was verified by experiments.
