Claim Text:
1. A high frequency X-ray generator comprising: an anode voltage generator configured to generate a first high voltage; a cathode voltage generator configured to generate a second high voltage having a same waveform as the first high voltage, the second high voltage having a different phase by 180 degrees compared to the first high voltage; and an X-ray tube configured to generate an X-ray by the first high voltage which is applied through an anode terminal and the second high voltage which is applied through a cathode terminal, and wherein each of the anode voltage generator and the cathode voltage generator comprises: a voltage generator configured to generate a voltage through a multiple switching circuit, the voltage having an AC type and a predetermined frequency, the multiple switching circuit comprising a plurality of resonant inverters; a high voltage tank configured to generate a first high voltage for the anode voltage generator or to generate a second high voltage for the cathode voltage generator by multiplying and rectifying the voltage; and a feedback controller configured to perform a feedback operation by controlling the multiple switching circuit of the anode voltage generator or of the cathode voltage generator based on the first or second high voltage which is applied thereto; wherein each of the resonant inverters is driven at a phase which is different from the phase at which each of the other inverters are driven; and wherein the anode voltage generator and the cathode voltage generator are physically separate voltage generators.
