X-RAY HIGH-VOLTAGE DEVICE AND X-RAY DIAGNOSTIC IMAGING DEVICE EQUIPPED THEREWITH

摘要

The X-ray high-voltage device is provided with a transformer, an inverter for converting a direct current voltage into an alternating current voltage, a rectification circuit for smoothing the alternating current voltage and supplying a direct current voltage to an X-ray tube, a control unit for controlling the inverter, and a resonance circuit whereof the constitution includes the transformer. The frequency of the alternating current voltage applied to the rectification circuit is set to be (natural number + 1) times the frequency at which the inverter is driven by setting the resonance circuit in such a way that the frequency of the resonance current that is supplied from the inverter to the resonance circuit is (natural number + 1) times the frequency at which the inverter is driven.
