Re: magnetic quenched triggered gap

By "pulsed operation", do you mean a means of modulating the operation
of the gap on and off?  Assuming you have an AC power supply, you'll fry
your HV supply or cap if your gap ceases to fire frequently enough to
prevent mains resonant rise.  Regular periodic operation of the gap must
never be interrupted.

hi gary,
no im not modulating it. ill explain my system as i should have done in the begining.
ill be running a transformer rectified into a large filter cap then running bursts of the chosen breakrate. this should allow me to utilize the much higher power in the cap than from transformer alone. of course it will be visibly pulsed but thats fine.
this idea isnt new and iv had quite a few email discussions with john freau on the subject as he built one called the compound storage coil.
john used rotary gaps(one fast one slow) i just liked the idea of easier control.
cheers
colin
