Patent ID: 8542798

Claim:
An X-ray imaging apparatus comprising: a condenser charging unit for receiving DC power having a first magnitude of a battery unit and generating DC power having a second magnitude; a condenser unit configured to be charged by the DC power having the second magnitude generated from the condenser charging unit; a control unit for sensing the magnitude of the charged power of the condenser unit and controlling the magnitude of power applied to the condenser charging unit from the battery unit; a high-voltage generating unit for generating high-voltage DC power using the charged power of the condenser unit; and an X-ray generating unit for generating X-rays using the high-voltage DC power generated from the high-voltage generating unit, wherein the high-voltage generating unit is configured to receive the DC power of the battery unit and the condenser unit which are serially connected to each other and to generate high-voltage DC power using the DC power of the battery unit and the condenser unit.
