In a simulation I have been able to prove that the gated pulse at resonance would actually charge a capacitor with a higher charge.

See attached image.  There is a switch beside a relay that is being pulsed at 200hz.  The resonant frequency of this circuit is 1.047khz.  When the switch to activate the gate is off (closed), the max charge of the cap is about 50V.  When the switch is opened, allowing it to gate, the cap charges to over 80V.  The step up transformer is a 1:4 and the source voltage is 14V.  Changing the duty cycle on the gate up to 90% increases the cap charge to up to 110V.

Even further to this.  If you decrease the impedance of the transformer from 900mh down to like 45mh, when gating, the cap voltage can reach >3kV!

900mH-->45mH.why? bemf come from coils,more winds is more bemf?

thanks

I presently cannot answer why.  But in the simulation this holds as true.  Try it.

Hi guys, i trying to understand what are you guys talking about, but i never understand..anythings
can you tell me in picture of the Frequency Generator, the most durability Gated Pulse Frequency Generator Schematic.
because i want to build 1, for my experiment.
thanks alot guys

The schematic is on the first page of this thread.
