Abstract
A flashlamp circuit includes a charge reservoir that receives a first voltage from an external source. The charge reservoir is coupled to a resonator and a plurality of discharge capacitors to provide a second voltage to the plurality of discharge capacitors that is greater than the first voltage. A switch is disposed between at least one of the discharge capacitors and ground to selectively charge the at least one discharge capacitor based upon an input to the switch. Discharge energy is passed from the discharge capacitor(s) to a flashlamp through a discharge bank without passing through any inductive elements. A bleeder circuit can be interposed between the power supply and the reservoir to discharge the reservoir upon shutdown.
