Earl's Corner

[MarkSnoswell]

Hi Earl,
    I am going to try the Avalanche pulse generators. Quite apart from the fast pulses I like the efficency of these -- nearly all the energy goes into the pulse.
One power loss that people overlok is the Mosfet gate drive. At high frequencies this can be the dominant power drain in an efficent output switching configuration. A triggered Avalanche pulse generator uses almost no power for the trigger.

Inspired by the avalanche pulse generators I am also going to try the same RC supply scheme on my regular Mosfet output stage. Doing this I can drive with square wave and control pulse width and energy with the pulse capacitor (pulse forming network - or coax).

cheers

mark.
