DC to AC

  1. Jan 29, 2009 #1
    Hello guys
    Does any one know how to change from DC [Direct current] to AC [Alternating Current]?
    Which circuit did I need to use?
    I will use it for my solar panel … it only generate a DC and I need to change it to AC
    A web sit …blue print of the circuit … any thing will be good

    is it possible

    Well, that's gonig to be tricky. Do your panels put out enough power? AC to DC isn't hard because you're often going from 100 watts to 1 Watt (eg: 110VAC @ 1amp to 12VDC @ .8amp) but gonig the other way, you're starting with just a few watts.

    Anyeay, Google power inverters.

    An oscillator is such a converter. You can also drive a transformer with an oscillator to step up or down the voltage.

    It's probably best to start by looking at commercially-available inverters:


    We had a thread a while back here on the PF about the optimum power point for solar panel inverter operation, but I'm having trouble finding it with searches (including google's site: Advanced search).... The optimum power point converter adjusts the Vin and Iin operating point of the solar panel, to get the optimum power output.

    Oh. Ah. I stand corrected.
