摘要： A method of controlling a power system of an X-ray tube is provided to supply power to the X-ray tube and control the emission operation of the X-ray tube. The method includes following steps: First, it is to judge whether a high voltage operation of the X-ray tube is started up. Afterward, a high voltage reference signal is gradually increased when the high voltage operation of the X-ray tube is started up. Afterward, it is to judge whether the high voltage reference signal is increased to an upper limit voltage level. Finally, the emission operation of the X-ray tube is executed when the high voltage reference signal is increased to the upper limit voltage level.

摘要： An inverter apparatus with overcurrent protection control includes a first terminal of a DC input terminal connected to an AC output terminal through a first switch element and a second switch element, and a second terminal of the DC input terminal connected to the AC output terminal through a fourth switch element and a third switch element. An intermediate potential terminal is connected to a fifth switch element and a sixth switch element, and connected to the AC output terminal through the fifth switch element and the second switch element, and connected to the AC output terminal through the sixth switch element and the third switch element. When the control unit determines that the inverter apparatus is in an overcurrent state, the control unit controls a sequence of turning off the inverter apparatus to be the second switch element, the first switch element, and the sixth switch element.

摘要： A power system with a power apparatus for an X-ray tube is disclosed. The power system includes an X-ray tube and a power apparatus for the X-ray tube. The X-ray tube has a cathode and an anode. The power apparatus includes a first power conversion unit, a second power conversion unit, and a power switch unit. The first power conversion unit produces a positive voltage and a driving voltage and the second conversion unit produces a negative. When the power switch unit is turned off by the driving voltage, the power apparatus outputs the negative voltage to suppress electron flow energy generated from the cathode of the X-ray tube, whereas the power apparatus outputs the positive voltage to provide electron flow energy to the anode of the X-ray tube when the power switch unit is turned on by the driving voltage, thus producing X-ray.
