Abstract

A high-voltage power supply for a microfocus X-ray tube with the output-voltage adjustment range of 30–80 kV at a power of 20–240 W (the X-ray tube emission current is up to 3 mA) was developed. The source is based on a resonant voltage converter that provides switching of power switches at a zero voltage or a zero current. The source uses a method for controlling the output voltage by changing the supply voltage of the resonant-converter power stage. The use of the Silagerm-2106 modern organosilicon compound for high-voltage insulation of the circuit elements made it possible to additionally reduce the size of the circuit and place it together with the tube-cathode power supply and the module of communication with a PC in a standard 19-inch housing; the mass of the device is 21 kg.
