Abstract:

A new energy store, the Compensated Pulsed Alternator CPA, promises to be a cost effective substitute for capacitors to drive flashlamps that pump large Ndglass lasers. Because the CPA is large and discrete, it will be necessary that it drive many parallel flashlamp circuits, presenting a problem in equal current distribution. Current division to - 20 between parallel flashlamps has been achieved, but this is marginal for laser pumping. A method is presented here that provides equal current sharing to about 1, and it includes fused protection against short circuit faults. The method was tested with eight parallel circuits, including both open-circuit and short-circuit fault tests.
