This circuit adopts 12V battery power supply, after Q tube oscillation circuit and step-up transformer T1, then it is half wave rectified. 12V battery voltage will rise to 450V DC voltage by converting circuit, charging to C1, it outputs about 5000V high voltage pulse to add to the trigger electrode of GEET-118 xenon flashtube by the trigger of SCR rectifier and the boost of T2, then the xenon flashtube will turn on with 1/s, discharging the energy stored in C1, to produce bright flashing.
