Re: [EVGRAY] Re: Capacitive coupling of energy.

Sven,

You are correct about this point and one reason why high impedance loads 
are easier to deal with as the tuning or filter capacitors can be 
smaller as you said.  Another reason Hectors designs use the highest 
voltage windings for a low voltage use so we don't burn up the energy, 
prior to storing/extracting in the capacitive load.

Sometimes with a current source on a MOSFET source follower for instance 
the drive impedance becomes very high.  Below is an article about MU 
followers which may provide some food for thought.

Also someone on here mentioned about regenerative and super regenerative 
radio circuits.  These are very interesting and important ways to use 
positive feedback as a multiplier as with such designs at the very high 
gain settings the super-regen frequencies show up and begin to quench 
the oscillation.  It is a fine line between quenching and adding some 
useful harmonics to pull more energy out of the matrix.

Keep up the solid work!
