    Re: need ckt diagram of 5kw SMPS inverter

    Of course it is, because they sell such things. But
    schematics, I have none.

    What I would recommend, is a scheme where the
    powertrain is modular / parallel with some reasonable
    inherent current-sharing. If (say) you stuck to a 1kW
    unit power stage, you'd have something that could
    comfortably run off a single lead acid battery (with
    sensible wiring sizes, continuous amperage in the
    battery and so on). Then if the outputs were "gangable"
    you would deliver the output voltage at lower current
    (less copper, maybe standard house wiring) and not
    have to deal with the 400A input problem on one
    very fat cable.

    You can see such inverters advertised for solar energy
    applications, sometimes with charge management as
    well. You might want to search by specific model and
    maker "tags", for your schematics or reverse-engineering
    info.

    Even if you do not succeed in this, if you want to go
    to high wattage , using powertrains paralleled at the
    gate and the transformer output can distribute the heat
    a lot more nicely than a single heavyweight. And your
    rating becomes a matter of simple addition and many
    cheap components, rather than the top end and high
    power density (hence difficult thermal management).
