ABSTRACT:
A power supply circuit for a flash lamp delivers energy to the lamp in increments rather than in the conventional single charging pulse. A dc voltage power supply is used which has a voltage output considerably higher than the normal lamp voltage. The power supply output is connected across at least two circuits which are adapted to charge to some small increment of the total lamp energy requirements and then to discharge the stored energy into the lamp. Each circuit which contains a low value capacitor is cyclically connected between the lamp and the dc supply so as to create a continuous series of incremental inputs to the lamp, the inputs terminating when the desired lamp energy output is achieved.
