Here is what I have: high power pulses (I~25A=constant, V~50-80V, t
=300us, rep. rate=100Hz; the pulses come in bursts, long term average
power is low). Input voltage is 10V.
Flyback converter is working fine recharging energy storing capacitor
at the moment. It's hand held instrument, I doubt I can fit much more
than 100uF capacitor, converter output is 200V now.
I was asked to increase power by factor of 4-6 (2x current, 2x
frequency...). ~250W power bursts, that is.
I am looking for the solution right now. Any suggestions how to
recharge the high voltage capacitor from 10V power rail quickly
(professional photoflashes/strobes may be doing something like it)
will be appreciated.
Thank you!
