    Hello All,
    I have attached a drawing of the setup i'm trialing at the moment, most will recognise that the triggering method of the SCR is not my idea. I can't tell if it is protected or not, it doesn't appear complicated enough to patent. I haven't had full sun yet to fully test for problems. I am concerned about panel damage. I can't get a reliable trace with my scope i'm still learning how to use it.

    It appears to me that this arrangement can produce cop>1 even when in a steady flow state, though I have no way to confirm this with my poor equipment, it would appear to be about 110% cop though I don't know why. The surging effect can be induced at different output level ranges by altering the capacitance.

    This seems to me to be the most basic way I can increase panel efficiency. It could be useful for some.

    The use of a slowly increasing "Source" voltage to
    "trigger" the Thyristor (SCR) is as old as the device
    itself and is not a "protected" concept. In fact,
    virtually all schematic diagrams released for public
    consumption are free to be used in whatever manner
    you like. Only when a circuit is intended to be used
    for "commercial" production or "monetary gain" would
    there be any possible "conflict" with the circuit originator.

    As shown, the SCR would be "triggered" when the
    capacitor bank voltage rises to about 1.8 Volts greater
    than the battery voltage.

    In order to permit the capacitor bank voltage to
    increase to a higher level before being "dumped"
    into the battery you could simply add more diodes
    in series from Anode to Gate for the SCR. Or a
    low voltage Zener could be used there.

    For purposes of battery rejuvenation or desulfating
    of a lead acid battery (12 Volts) you'd want the
    voltage to increase to about 20 Volts for best
    effect.

    It's about as simple a circuit as one could hope for
    so you've done well.

    The diode you've shown in series with the output of
    the Solar Panel is adequate protection.

      Thank You for that SeaMonkey,

      It is difficult to me to understand but when the surging output goes above the rated max output of the Solar panel could it cause damage that way?

      I would have prefered to test it myself but won't get a chance for some days because of the weather. I wouldn't want anyone to damage thier Panels.

      I do have idea's about how cop>1 could be possible even with such a simple setup, but i'm still trying to learn the correct way to explain my thoughts.

      Regards

        A panel which is designed for a 12 Volt system
        will typically produce 20 Volts or slightly more.

        The panel is generally not capable of producing
        more than a couple of amperes at most and
        is capable of working into a "short circuit" without
        any damage. In fact, they are rated by their
        ability to provide current when working into a
        short circuit.

        With your battery pulsing circuit the Panel is
        effectively isolated from the capacitive
        discharge pulse which is applied to the battery.

        If, however, the SCR should happen to "latch"
        continuously "ON" then it would be necessary
        to insert an inductor into the circuit between
        the panel diode cathode and the capacitor bank
        to limit the panel "surge" current.

          The only thing that could kill that panel..

          Is if it caught fire. The capabilities of the panel are quite solid. It can only go so far. as far as backing anything up into the panel, if you are worried then protect it with a diode on both lines. Panels can be expensive so a 10 cent diode isn't that much to protect your investment.

            tune it up

            The last two paragraphs were not actually intended to be directed to you in particular just a statement I thought important.

            I am not distracted by overunity. Even if I were to find it, i'm not sure it is so important it should distract me, or make my life less enjoyable. My actual electrical power needs are quite small, but I could think of many uses for free power.

            I won't be tuning anything I do not understand well. It would be difficult to tune something in sync with the irregular events of nature anyway to say the least and I have no way to achieve it at the moment. I would rather not try.

            At the moment I am seeing a great many tons of water moving from the sky to the ground then the sea, I would rather not to try to control or tune that in the same way. Though it could do a lot of work for me, It could be dangerous for me and others "downstream" so to speak. I only manipulate what I have to or need to, to do otherwise seems pointless to me.

            Regards

            Since I'm pretty sure Bedini pays an electric bill, he himself is not energy independent. I have constructed a Newman, a Bedini(s), a Gray, a Marks, a MEG and many others over the course of the past 20 years. I have dreamed that at least ONE, just ONE, would run away and blow up in my face. Then ONLY would I know for sure that energy extracted from whatever ... ZP, Aether is real. I would be motivated THEN to figure out how it ALL REALLY works. Tesla was not energy independent either.

            I suggest you go for broke and tune it up and see what happens.

              And....

              And how do you know Tesla was not energy independent...

                Ha Ha Tesla energy independant ! I think it's a safe bet he burned up lots more than he made, but he used it well.

                Anyway I swaped my meters from back to front and the extra watt dissapeared , bit of a relief anyway.

                I added a couple of diodes to the gate and jumpered them with a switch so they are optional. The extra diodes make it dump at about 6 volts above battery voltage or 1.2v when jumpered out. I managed to pump up my small 28 Ah emergency bank today (4x7Ah) to 15.3v. Still cloudy.

                Still playing around with some very simple idea's for mosfets to try to free up the panel a bit more .

                Cheers

                  Farmhand,

                  not sure if this is exactly what you need, but, im currently using some STP80NF55 mosfets, 55V, 80A continuous (320A pulse)......and cheap !

                  hope this helps

                    Hi rave154, Every bit helps mate, thanks, that does has an impressive looking data set, I don't know a lot yet, still learning but that seems to be made for the job. Very rugged. It surprises me they can take so much for thier size.

                    Cheers.
