    Maybe it is better to scrap it from broken UPS. They contain very big transformer which should be more efficient. Replicating them or buy new would be expensive....

    Thanks for the info cikljamas. That look like a very simple inverter circuit. Is your output guaranteed at 230V? Since on my stingo experience, I get at least 50V at primary, and not sure if the output will be 220V if I use 12V/220V transformer.


    Good luck on stingo 2pnp too .

    cikljamas, You are a Ledgend, THAT is the alternating MOSFET switching circuit I seek. Thank you so very much. It can be done much better than that with only a little bit more complexity, as in better gate drivers maybe.

    Dual fets both side's for more power, better heat dissapation or just redundancy. Larger Toroidal transformer

    Wicked, that circuit could also pulse an opposing set of coils on a Toroid 180 degree's out of phase with a little modification. The pulse width would need to be reduced a lot for that.

    Awesome i'll check it out.
    Thanks.

    inverters

    Hi, guys !
    You like inverters ? Of course you do !
    Well, i found it very quickly on the net so i do not have to
    photograph it...
    This is one that i made twice (two of that same kind or two
    pieces, however you like), so it is twice confirmed that they
    work just fine, very fine :

    100 Watt inverter circuit Electronic Circuits-Circuit Diagram-Electronics Projects-Design

    Transistors are getting hot after 10 or 15 min., but i think
    it is normal for average consumption of 1,7 Amps, as i saw
    on the meter comparing draining between this inverter and
    three stingos lightening my cfl day before yesterday...

    But looking on the net this schematic i stumbled upon this
    one, even simpler, with just two mosfets :

    Inverters & UPS Electronic Circuits-Circuit Diagram-Electronics Projects-Design

    Since this one uses the same chip it looks very promising
    to me, and if someone wants could give a try and check
    it too, and maybe even before my tested (first one), and
    if something went wrong you could still come back to my
    tested circuit with six 2n3055s...

    I am giving above suggestion cause it is simpler circuit
    and could spare your money and time, and it just looks
    very promising to me, and i am convinced that you are
    going to have same impression as soon as you see its
    schematic...

    So i was looking for the diagram of my tested version,
    and on the same page i found maybe even better one...
    That is how i like the day to become...
    And after i hear in morning news that flood in Australia
    is dropping the day is going to be even sunnier to me..

    Sucahyo, today is your two tip 32 circuit on the bench !
    Thanks for your confirmation that it works fine !

    Concerning my cfl - transformer combination :
    Output of the stingos goes to secondary of 220/ 12 0 12 transformer,
    and primary of the transformer goes to cfl !
    I hope i answered your question in the best manner !

    Cheers !

    cikljamas, These inverters sound very good, can you give me some specific informations about these. Do you mean you made a couple of 12v to 220v inverters. I am very interested in that.

    If you need specific informations about that inverter i will provide it
    for you since i am very satisfied with these (i made two of them-same
    kind, just two pieces) inverters...I bought one in the store (300 W) with
    fan but that inverter (from the store) just drains too much power from
    the battery, if you ever decide to buy one, i suggest you to buy 150 W,
    instead of 300 W, or more in case that you need inverters for ordinary
    purposes...
    Cheers

    You mean you put the 12V-12V part of a 220V/12V CT transformer as load?

    That is still amazing .

    Thanks Sooner or later I would need an inverter .

    The comparison of consumption is really helpfull since it means that we end up doing better eliminating inverter . Might as well convert the electronics in our house to DC if we use solar battery lol.

    Yes .

    I currently use it to spin harddisk, to see how long it can run. A broken battery power it for about three hours, so I think it is good.

    I played today with stingos and cfls, and this is the result :


    Is it 1 A for 20 W bulb to much in your opinion ?
    I compared stingo and one home made inverter and for the
    same bulb stingo drains 1 A, and inverter drains 1,7 A...
    1 : 0 for stingo (three stingo to be honest, but three stingos
    are still stingos, am i right ? )

    Cheers !

    1A is good enough . But I think you can still tune the circuit. I found that with high impedance output, the 500K pot may not be necessary.


    Thank for the inverter information . That is really usefull .

    Mostly because of the component price.

    The component requirement is a bit high and expensive too. I prefer not to toy with expensive component until I really know what I am doing.

    Notice how many farad the capacitor are, and I don't think 250A pulse is a joke.

    The circuit is rarely discussed. I am not aware if there are someone who try to replicate that circuit. The commercial product, fairly new lineup:

    Toddler toy donut easier here. I have donut that work on timer driven version but do not work for stingo. Maybe because stingo require high inductance.

    Thanks for your observation in "this is it thread" regarding bedini circuit...
    I spent a lot of time today trying to figure out this circuit :


    Could you maybe help me with posting one of yours tested bedini solid
    state radiant charger schematic ?
    Unfortunately, I never try that.

    The principle is to pulse the cap, wait a while, then dump it to battery. The waiting part is important according to Bedini. On Bedini patent drawing, there should be delay between charging and dumping, because of the use of optocoupler. Optocoupler react in miliseconds. It is often mentioned that the commercial one is tuned down, meaning that we should do tuning to get OU.

    I think ctglabs replication is different because it do not wait a while. May not work the same.


    Ben have generously given me part required to replicate that circuit, so I will be replicating sooner or later. Although I may have to wait until I have scope.

    You still use mosfet? because you may need to change/remove some component if you use transistor instead of mosfet.

    Those SG3524N chip are appear often on Bedini design. It seems Bedini trust that chip better than 555.

    The problem is we still do not know how to tune the device and what to do to tune it.

    Bedini circuit need tuning. The first time I found stingo can reduce consumption on load on any condition, I am surprised. Sorry if this make you think that all bedini circuit are like that.....

    But even with unconditional "resonant" (see gmeast comment on reduced input) stingo still need tuning too.
