In this paper introduced a design that applicable for normal spark gap could operate in high repetation rate. In this design the capacitor charged with low voltage by using a thyristor switch that will be discharged through pulsed transformer primary and on secondary caused charging of main capacitor. Max capacitor voltage will be received on specified time and then turn on spark gap and all of main capacitor energy discharged between electrodes space. This composition component can solve problems same as timing charge for capacitor and charge recombination in spark gap space and result on disappearance repetition rate limitation.
