Abstract:
1. An X-ray apparatus comprising: an X-ray tube; a generator configured to provide a high voltage to the X-ray tube; a power battery configured to supply the generator with voltage; a capacitor bank parallel-connected with the power battery; a voltage-voltage converter connected between the power battery and the capacitor bank; a control logic circuit capable of controlling the converter; a first voltage sensor parallel-connected with an input of the converter and configured to measure an input voltage Ve; a second current sensor series-connected with the input of the converter and configured to measure a current of the power battery; and a third sensor connected to an output of the converter and configured to measure the output voltage of the converter, wherein the measurements made by these three sensors are transmitted to the control logic circuit, and wherein the control logic circuit comprises a duty cycle regulator capable of making a predefined duty cycle vary in order to regulate and optimize a current of the power battery and an output voltage of the converter.
