    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.

    Don, A26 you didn't label it...is it a 74122???

    (http://www.globalkast.com/images/tonywoodside/Fig.6-values.png)

    74123 will work better because the inputs are combined within the chip instead of tying them together outside like pins 1&2 and 3&4
    ali can you came up with a schematic for the 74123 similar to Stan's?

    this play with bemf,TS.but switch from secondary,Is the same frquency of relay(200hz)?maybe this is the real circuit of Stan.

    Do you know about Triac of Meyer's Part?

    gated at short duration(90-95duty cycle,5-10% gated),mean high voltage high amps(from Bemf) short duration.

    -when you write patents,you must use trick word like "Switching Diode" to keep secret. i know that picture is diode why explain and place name "switching doide"???use 10khz but use switching diode(for high frequency)?normal diode(1n1198,1n4001-7) can operate at over 50khz,why use switching diode? what do you think?

    How an earth the pulse output of the 74122 should look? see att.

    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
