This shows how simple to convert dc to ac, running at about 60hz....

Somebody deleted the video :(

What ways are there to convert DC power to AC power?
I'd be happy to use a square wave that could be amplified to a higher voltage and low current, to use in the Newman, but the method is elusive.

Using a commutator or relay or mosfet H-bridge. It is the Secret of DPDT.

Once you understand how to wire a doublepole, doublethrow toggle switch to reverse the polarity of DC then you will understand the commutation method.

Thanks guys, you have given me something concrete to go on.

Nice demonstration board/circuit by the way :)

Special "negative" LED`s :D  lol

I suggest that you put the MosFet tutorials in a group on youtube or links to previous and next videos in the series.

This reminds me of a simple grid tie inverter using just a few parts . never tried it myself as i use bought ones with island protection at my home . is this what the video detailed . http://www.neo-aerodynamic.com/GridTieInverter.html
