The Main Reason for this Unusual Supply method: Is the Voltage from the Transformer is an AC Signal and Higher than the original 12 Volts. So it Supplies a Stable 13 Volts to the IC, Even if the battery Falls below 12 Volts when the Inverter is in Operation.

very cool. gary, I tried to email you recently, and had no luck. has your email address changed? I have a request for a new project. its a tester to test electronically commutated motors. there are several on the market, but I bet you can design one. regards,pg.
the motor in question is almost exclusively used in home central a/c units. needless to say, they are numerous in s. florida. the cost to replace one is over $1000. having a problem getting my inverter to work. I've hooked it up using a 24vct 450ma transformer just for a test. B+ to chips is only 4v. what would be a good way to troubleshoot this circuit?
