A strobe trigger pulse generator includes a power supply, an energy storage capacitorcoupled to the power supply and a trigger pulse generator which intermittently generates trigger pulses to energize a trigger pulse transformer. The pulse generator includes a trigger capacitor having first and second leads, the first of which is coupled to the trigger pulse transformer. A trigger capacitor charge circuit includes an input terminal coupled to the power supply and an output terminal coupled to the second lead of the trigger capacitor to establish a current flow path between the power supply and the trigger capacitor to direct a charge current to the trigger capacitor. A trigger capacitor discharge circuit is coupled to the second lead of the trigger capacitor to periodically direct a discharge current from the trigger capacitor through the trigger pulse transformer to generator a high voltage trigger pulse. A discharge current disabling circuit is coupled in series with the flow of discharge current from the trigger capacitor discharge circuit to selectively block or conduct the flow of discharge current from the trigger capacitor discharge circuit.
