Abstract
This circuit facilitates the triggerability of a remote three wire flashtube and trigger coil assembly at a much lower than normal anode power supply voltage. The discharge of the trigger capacitor produces the usual trigger-event in the trigger coil. Simultaneously, a trigger boost capacitor boosts the flashtube anode voltage to approximate the supply voltage plus the voltage across the trigger coil primary winding. As a result, the flashtube anode voltage is essentially doubled at the outset of each trigger event.
