  • I also have to report that my battery lost 0.06 Volt running all night.
    But as was pointed out, this is the record holder in simplicity for
    a low-price desulphator and charger. So Groundloop has really made a nice circuit.
    Will continue to experiment with it too with introducing different components.

    EDIT: I am wondering if there is an electronic circuit strategy, that would cut off
    everything except the radiant spike, because during the rest there is energy dissipated in the wire resistances.

    Maybe a delayed gate signal for another MOSFET that shuts the line right after the spike occured.

    EDIT: I have to elaborate on that. Of course this would not work with Groundloop´s circuit, because
    that would kill the oscillation.
    Maybe more like Plengo did it with 2 555 timers. One for the gate signal and one for the delayed gate signal.
    Or maybe just a single MOSFET with a super short pulse duty cycle.
    I will experiment with that a bit.

      I noticed that with my setup too; the oscilloscope showed the charge battery voltage falling after the spike was over. It would be interesting to see if a capacitive dump into the battery at that point would overcome that.

      I'll be watching with interest Xeno

      REALLY wish I had the time to build, and REALLY appreciate everyone spending their time with this, I hope everyone else is finding it as rewarding and fun as I am

      • I shaped the signal now like this :

        Now it needs to be tested if that draws less current to operate the circuit than the radiant charge can charge the battery.

        • @Inquorate:

          Can you give me your opinion on how to best collect the radiant energy with diodes from the coil?
          I have a single coil through which a short current pulse is sent.
          Thank you.

          • Hi all

            I've tried the last circuit "closed loop test" with a single battery.
            Previous core and new core with twisted wire. No apparent differences.
            Resistor 180 changed, normal carbon 1/4 w.
            Bat 12v7A: 11.4v
            10kmF/16 -> 9500mf/50

            Results: Connecting and voltage drop to 11.26v, after 4 1/2 hours drop to 11.17v. After 14 hours 10.87v. After 18 hours 10.76v. After 24 hours 10.76v.
            I think my batteries are not sulfated.

            @Groundloop
            At 10.76v the mosfet not oscillate, right?
            I do not understand the circuit operation
            I'll look into the above scheme to understand the operation and connections for use with PSU.

            @ewizard
            Some time ago I tried this circut, I remember having discussed with Groundloop. Works fine, but this other version works better, also uses only one inductor and mosfet-N:

            @Xenomorph
            It refers to a single battery or separate battery?
            I understand that you want to separate only the radiant component, right?
            What is the purpose?
            To quantify?

            @Inquorate
            In his theory argues for direct charging 60% and 60% for bemf, right?
            I think that 60% of direct charging would be for DC, not pulsed DC.
            You have measured and taken into account the loss in the first pulse?

            • @torpex:

              The goal is to use as little current as possible to switch a power MOSFET with a very low duty cycle signal that also does not use much current to create radiant spikes.
              Only one battery is used.
              I wanted to see if it is possible to minimize current loss while gaining charging.
              Bedini said multiple times that charging a battery with radiant while it is supplying a circuit is not possible, but i simply want to verify that experimentally.

              Desulphation circuits are not designed to consider charging, they use the bipolar 555s that sink more current.

              The problem that i run into is that when i use a CMOS 555 timer then the output current is not sufficient to fully switch the MOSFET, but any kind of gate driver would consume too much current. The cat chases its tail here.

              I`ll try some logic-level MOSFETs next, maybe that works.

                I understand. Perhaps a starting point might be to use one's own self-sustaining pulse to the gate of mosfet and an extra circuit to start it.

                I believe he refers to is not the most effective.
                In my opinion it can be to collect with capacitors. The trick will be done without loss. Or maybe the radiant energy levels needed to operate different ground or voltage reference. I'll look in my notes, I remember a scheme on ideas in this goal.

                • @torpex,

                  >>At 10.76v the mosfet not oscillate, right?

                  The oscillator need a higher input voltage than the load at the coil
                  when run as a normal battery charger. I use 16,5 Volt input voltage.
                  This will keep the oscillator running when the battery being charged
                  is climbing in voltage.

                  • I have built a circuit with a CMOS 555 timer and a logic-level gate MOSFET that i checked with duty cycles of 3% to 7%.
                    Unfortunately the battery voltage was dropping slowly.
                    The idea is to create on a solid state level what Tesla realized with his quenched spark gaps. Very short unidirectional impulses.
                    Maybe Bedini was right that a battery that is under load, can´t be radiantly charged.

                    EDIT: With this configuration for the 555 resistors and cap the voltage
                    stays at the same value fighting hard to go up, so that is probably
                    close to the equilibrium.



                    Best signal so far @ 3kHz 2% duty-cycle with high resistances on the 555

                      I mean to minimum voltage (not for PSU).
                      My circuit still runing, 52 hours: 10.74v. Why does not drop more?
                      I understand that 16.5v is appropiate value for charging 12v with PSU.

                      @Xenomorph
                      Very interesting scope-shots. You are pulsing the coil circuit description for groundloop?
                      Both schemes of desulphators have the property to collect BEMF in the battery itself. They can work without charger (charged battery).I use both circuits.

                      It is likely that bemf and radiant not the same. I remember having read in motors issues (maybe Ossie C.) that cable lengths affect and are obtained weird voltage readings.

                      • I use this very simple circuit :



                        Uploaded with ImageShack.us

                        Just a 555 timer creating the gate signal for a LL-MOSFET.
                        The signal can be much better kept short that way to prevent unnecessary current flow.

                        No OU possible this way. Something non-linear needs to be added to create
                        a higher charging than discharging.

                          This circuit can not recover bemf. BEMF generate at L1, BY-255 short that. The + battery are the - for recover. I think so ...

                          I propose:
                          Bat1 12v Source (midle charge)
                          Bat2 12v Charge (midle charge)
                          Bat3 for cmos-gate current

                          In scope show 2 channel bat1&bat2

                          1 test voltage readings Bt1-Bt2
                          2 test current readings Bt1-Bt2

                          This way we can measuring input / output but separating the driver consumption.

                          For BY-255 other ultrafast diode.

                          • So how would you connect another ultrafast diode to a single battery in your opinion? You mean the diode should be connected to the minus rail of the battery?

                            • Guys could you do me a favor?

                              Guys that are seeing a voltage gain in the batteries and then it stops. Could you do me a favor and put a fan blowing air on your setup including all your batteries.
                              I believe you are getting a stalling of the charging effect because of poor environmental conditions while charging. Like the area gets depleted of something. I was wondering if you could blow the air around creating a more circulatory nature around your device and batteries. I say this because Tesla used puffs of air to make arc gaps run faster. So it would be an excellent experiment to see if it does in fact change your results.

                                I have doubts about the path bemf, in first desulphator i understand the path, but in second desulphator i do not understand the path, but both circuits operate. May be similar to the second circuit.

                                I propose this little proof for measure spikes (see if there are) with voltmeter across 15nF cap.

                                The replacement of the diode (ultrafast type) is to ensure that it is fast enough.

                                @Jbignes5
                                All testing is interesting, but I do not think it affects. In this circuit we have no spark. Or it may be because the temperature affect the charging? U tried it?
