    Good day,
    Can anyone send me the gerber files of Mr.Bob Boyce? The PWM3G files which i suppose they are the gerber files so i can print them on a PCB. Does anyone have them? On ''hydroxy'' group on Yahoo, apparently nobody has them... I wonder how can that be? Mr.Boyce shared them on the ''Working WaterCars'' group on Yahoo, publicly. There is a document on google called ''pwm_1.pdf'' in which this is stated:

    ''This Group ( http://tech.groups.yahoo.com/group/WorkingWatercar/ ) has been given permission most graciously, by Mr.Boyce to present a compilation of his project so that it may perhaps be more easily understood and replicated by the general public.''

    Bob was here and tested this circuit, use 3 of them together.

    Thank you very much!
    The post remains open though. If someone has what i asked for please, you know what to do.

    Thank you,

    I gave you the link to the kit. HYDROGEN GARAGE he has the circuit. PWM3G kit comes with
    circuit dia. or maybe you lost your circuit diagram? And layout? Ask.

    His name is Andrew.

    Ok, i will ask them for the circuit diagram.
    One question i have, the diode in the above circuit isn't connected and it would appear that there is nowhere to connect it to. It is a special kind of diode, i don't think it's available in my country... Where do i connect it?

    WOW!!!! That is so good
    So this circuit itself is designed by Mr.Boyce?

    Thank you very much for your kindness!

    Yes Bob and Rich are friends and Rich worked on it for me. I spent
    $500 for the job well done. I put it in a box later. This one can
    run 50amps on a 3 phase motor starter too. It is not going to
    break down using it on water experiments. My favorite design.

    I am the only one with this circuit.

    It is a very simple circuit but you need 3 of them ganged together and set
    the duty @ 2.5%- 5% - 10% respectively. This is somewhere to start

    Every box will need tuning and this circuit makes it a dream come
    true for a wide range.

    You are much too kind, my good sir.

    Say what will the issue be if instead of the material T650-52 i use what i can find in my country, T650-26?
    Because as far as i can remember this one is the replacement for the 650-52. Am i right?
    I think they have identical constructive and electrical properties except the fact that T650-26 cannot go as high in frequency as the T650-52.

    Will there be any serious problem if i use T650-26 instead of T650-52?
    Please tell me.

    Here it says:

    -26Materials
    The most popular material.It is a cost effective general purpose material that is useful in a wide variety of power conversion and line filter applications.
    -52Materials
    The material has lower core loss at high frequency and the same permeability as the -26 Material.It is very popular for high frequency choke designs.




    I strongly believe these two cores are interchangeable. I will buy the first one as the -52 isn't available in my country.

    Thank you again for your great kindness!!
    With your permission i would like to post these files which you gave me, on other sites such as Yahoo and YouTube. Only with your permission.

    Unless you have a 101 plate box it does not need the exact core so
    you will have to experiment, have fun. Yes go ahead and share the circuit
    with the box builders.
