yes i have a scope, meters and a good iron :)

and i would agree,, "why would anyone modify a perfectly good sinewave"?

lol

i also have a collection of high power parts, and also
have an industrial exide ups that is 15kwatt, 3 phase that i could canabilize for parts as well,, it has a 240volt dc front end which i have no intention of trying to feed. it has some hercan big parts in it that ought to be useful,, and maybe it could be modified for my intended use,, i dunno.

what i am wondering is
there are numerous schematics for square wave units, that seem to do the job they are intended for,, and they have internal triggering to get them somewhere close to 60 hz.  usually they use sort of a push pull arrangement to feed a transformer

what if one was to build a multistep push pull and instead of triggering the steps internally with descrete components one used a micro controller with various output pins to trigger each step.

anyone ever tried it,, or have a schematic for a microcontroller triggered inverter?
