The presented report contains the description of a high-voltage source with output voltage up to 60 kV with power up to 15 kW. The source consist of the converter whit IGBT switches, working with a principle of pulse-width modulation on 20 kHz frequency, and high voltage sectioned transformer with the rectifier. The schematic configuration and the optimal matching of the rectifier to the load has allowed minimizing the energy stored at the reactive components of the high-voltage stage at the level less than 15 J for 60 kV operation. The design of the high-voltage transformer provides preservation of working capacity at voltage up to 100 kV. A nominal output voltage of the source is 60 kV. The efficiency of system is more than 80% at the nominally output power. The controller of the source is developed with DSP and PLM, which allows optimizing operations of the source. For control of the source serial CAN-interface is used. The description of the source and the test results are presented.
