  • A failure can give you time to step back, clean up, and make a better driver.

    What mosfets were you using? Sounds like you just generated a huge amount of voltage and blew the mosfets, which then blew the pwm.

    • Hi 7, I'm using IRF740's on that. You might be right but it did seem to work ok until I stopped and started it a few times by just disconnecting the power to the PWM. I do notice with a lot of stuff that there is a big current surge when first powered up so maybe the repeated BEMF spikes did the deed, there is nothing to prevent it.

      Anyway I want to implement the current limiting feature of the SG3524 chip but since the output is remote the current limiting will have to be referenced to the input current, voltage divider or some such thing. Can't remember if the 24 chip has soft start or just the 35 chip.

      I only need to lower the coils frequency to 470 Khz to be able to use the SG3525 chip which is much better as you are aware. I won't go ahead and do anything just yet so if you have any more suggestions they are always appreciated. The SG3524 chip is good but it has different outputs to the 3525 chip. And that is where it failed, it actually spat out some melted plastic from between the outputs area. From memory the 3525 chip can run from 35 volts but still only pulses out 12 volts from it's output's but the 3524 chip has transistor outputs that collect from the supply rail and emmit the output.

      I think my best bet is to improve my toroid terminals and maybe wind some new bigger diameter coil "A's" and coil "C's" I've got two different set's of Extra Coil "B's" so that would give me two complete sets of two coils.

      A below 470 Khz set (I hope about 420Khz) which I can use a SG3525 PWM with and an above 1 Mhz set . If I set up the lower frequency set as transmitter and receiver then I might be able to get the other two tuned to work from a harmonic of them maybe the third harmonic. Maybe that is just silly but I'll find that out the hard way I guess.

      Cheers

      • Your experience reminds me of a PC I used to use last year. It was cobbled together and there was no 'On' button. I found that a dial from a radio worked well, inserted into the hole where the button should be and, if I left that dangling, could flick the thing in the morning and the PC would start up. Silly method that was supposed to be for a day or so til a repair could be made. I used the PC for about 9 months like that
        So, yes, perhaps a time to address a few things with the setup, if you've changed out many components on same wiring etc. In any case, best wishes for the repairs

        • Well it doesn't look all that bad, both mosfets 1 turn off transistor and the IC, probably a diode or two aswell.

          It definately looks like the mosfet failure caused the rest, most likely. The mosfets would have failed then the weaker of the two turn off transistors failed and alowed a path back to the output of the IC that way, then it failed and current went to ground along that path creating the smell. hehee

          Not a real big setback, I just broke my hammer. The bell is OK, thats the main thing, I can hit it with rock if I have too. As long as it rings.

          Thanks for the wishes Slider.

            • Hello Friends I am Antigraviticsystems1 and this is a small demonstration that it is possible to send small amounts of energy through this system, the thread that goes from one side to emulate the necessary connection of the respective axes of transmitter and receiver to the ground, having made the experiment in a flat I have omitted the ground pegs replacing them with a wire conductor has a resistance of 1000 ohms sandwiched emulating the electrical resistance between 2 good earthing far apart
              Hello antigraviticsystems1, I translated and quoted the desciption from you're video here, I hope you don't mind.

              Nice demonstration, very good result too, I like the idea of the 1000 ohms to represent ground resistance, very good. I should do that also. I will have to wait till it rains again to try the actual ground because I live on a hill and the ground is very dry like dust. Spring is nearly here downunder.

              Good work

                • Hello Friends here is a video telling you, I inserted a resistance of 1000 ohms in the cable that goes from sender to receiver to emulate the resistance between stakes driven into the earth mother that way we get a little more to the final experiment, another of the peculiarities is that by using this cable so little about the armor section of the transmitter-receiver parasitic capacitance is very small, thus it would emulate a very tall masts that would separate enough soil reinforcement by decreasing the parasitic capacitance of armor to the ground, here are some encouraging results ‪transmisión de energia electrica sin hilos, idea original de Nikola Tesla‬‏ - YouTube

                    • antigraviticsystems1

                      Do you have HV terminal of transmitter connected to long wire going to receiver and ground wire connected to metalic plate ?

                      Also : did you checked if any shield like wood plate, glass ,metal plate between transmitter and receiver upper terminals restrict effect ? Or by moving receiver to the another room ?

                          • another issue that really catches my attention is that if we consider the crust as a conductor finite, obviously if we hold these high electric potential should create electrical waves at particular points in the Earth's surface at those points where "the waves join "the electrical manifestations of the issuer would rise significantly to imagine that I have just commented you to imagine just a ball completely covered by water on all sides, if a launch point on the sphere pebbles at a certain frequency which should be closely related to the speed of transmission of the mechanical disturbance through the fluid and the cover would get ditancias visible nodal points where these mechanical disturbances are amplified, another idea that comes to mind is that by varying the components involved may be defined in point on the globe that wish that these disturbances were most notable in any way can lead this mechanical energy to any part of the sphere, if we work with the mechanical vibration resonant frequency of the imaginary sphere energy losses would be very small, good all this is the result of a rapid personal reasons, if I'm wrong .... I know you do a Greeting

                              Those mosfets are 400 volts, did you measure what the charging circuit capacitor voltage was? I bet 160 volts would get magnified quite a bit in voltage by the charging circuit.

                              I'm not so sure about the 3525 because it has problems below 2% duty cycle. I am actually thinking of building one of the inverting buffer oscillators again to see if I can get a stable pulse below 2% duty cycle.

                              The duty cycle is important because if a pulse is the width of a harmonic of the coil, the energy will harmonize with the existing oscillation better and thus drive more power into the secondary.

                              I also built an xr2206 pulse circuit that I get a solid 500 nanosecond pulse time no matter what the frequency, but I can't adjust the pulse width on that one. The xr2206 can take more than 20 volts, I think.

                                I want to build this. I need some more information.

                                What gauge wire is the secondary?

                                How long is the secondary?

                                What are the specifications of the transformer core?

                                Can you upload a higher resolution copy of this image? It is hard to read some of the smaller text.

                                Thank you. Very glad to have you participating in this thread!
