Abstract:
1. An x-ray imaging apparatus, comprising: a DC-AC converting part for converting a direct current of a battery to an alternating current; a high-voltage transformer for increasing a magnitude of the alternating current to output a high-voltage alternating current; an AC-DC converting part for converting the high-voltage alternating current to a high-voltage direct current; an x-ray tube having an anode terminal and a cathode terminal electrically connected to the AC-DC converting part, the x-ray tube generates x-rays by allowing electrons emitted from the cathode terminal to impinge on the anode terminal; a housing part for sealingly receiving the DC-AC converting part, the high-voltage transformer, the AC-DC converting part and the x-ray tube, the housing part filled with oil; and a capacitor configured to charge and discharge the direct current of the battery; wherein the housing part includes a side panel having inner and outer surfaces, the DC-AC converter part attached to the inner surface of the side panel, and the capacitor attached to the outer surface of the side panel; and wherein the side panel of the housing part is a printed circuit board configured to electrically connect the DC-AC converting part and the capacitor.
