Resonant charging type triggering device for rotary spark switch

The invention belongs to the technical field of high-frequency high-voltage power sources and relates to a resonant charging type triggering device for a rotary spark switch to solve the problems that in the prior art, a rotary switch cannot be easily conducted, the conduction dispersibility is large, and the reliable triggering and the high repetition frequency working of the rotary switch are seriously influenced. A rectification filter circuit is used for converting 220 V alternating current signals into direct current signals and storing energy; a full bridge circuit is used for converting the direct current signals into pulse signals; the pulse signals are shaped through a series resonant circuit and then boosted through a high-frequency high-voltage transformer to obtain high-voltage pulse signals; the high-voltage pulse signals are used for charging a load capacitor through a high-voltage rectification bridge, a spark gap is broken through when the voltage of the load capacitor reaches the self-breaking-through voltage of the spark gap, and the load capacitor discharges; an output feedback detection circuit is used for detecting the discharging state of the load capacitor; a signal control circuit is used for outputting a driving control signal to control the full bridge circuit to stop working according to the detecting result of the output feedback detection circuit.
