I just corrected a few errors in four of the circuits:

-Capacitors are no longer backwards on Inverter
-Ground added to power section on 12V to 24V DC-DC converter
-Power supply now includes note about using 120 ohm resistor instead of 240 ohm
-Op amp pin polarity corrected on low voltage alarm

Yep, the circuit still sucks. One of these days I will get around to looking through the large inverter topic and picking a few good ones for inclusion on the circuits page.

The base current for the 2N3055 transistors in the inverter is much too small for it to make any reasonable amount of power.
Yes it is crap!

The bases of 2n3055s are rated for -7V max, yet this circuit still applies over -20V to them. So it's still crap!
