Abstract: This work discusses the calculation of high-frequency resonant converters, the specifics of their operation, as well as the applicability of this topology to charge a capacitive energy storage device (pulse capacitor) in order to improve the stability of the powerful generator of nanosecond pulses "RADAN 303": reducing the deviation of its output voltage from the value set by the operator. The work of the converter with a series resonance is analysed in detail, including transients at the change of phases of the working cycle, an example of calculation of the elements of the applied electrical circuit is given. Also, methods of peak currents' reduction in the process of converter circuit operation are considered and results of research of dependence of output voltage of the device on input voltage (stability of circuit operation) are given.

Keywords: resonant converter, capacitive energy storage charge, high voltage pulse generator, high voltage power supply, resonant converter, capacitive energy storage charge.
