Ok, i've posted this idea a few places, and gotten a few verbal
slaps from snobby engineers for having birthed it... but i still think
it's workable.
Here it is:
A moderate power modular Class D device that can handle
plus and minus 12v (24v rail to rail).
A full H bridge of fets - probably 25 per device, 100 total, of IRF840.
Might need some current drivers for that many fets, I dunno; but
I figure 20khz is fine for switching frequency. Might be ok at the
lower frequency.
A series of 26 x 12v car batteries, center grounded (13 per side),
to power the circuit. Take the plus and minus 12v for the class D
driver chip from the two center batteries.
An isolated and regulated supply section and crystal controlled
oscillator to make a 60hz sine wave.
Negative feedback to lock the voltage into a range similar to
115/230v power lines.
And Voila! - a heavy duty AC power supply for your home!!!
Theoretically it'd be enough to run things like an oven, electric range, water heater, etc...
Then all you need is a metric-assload of cash to buy solar panels.
hehehe
Any comments?
