i did a test run on the inverter with the small transformer today, and it seemed to go ok. i havn't tried under load or anything as yet but i am happy with the idle current, it is 16.3w does that seem ok to you guys?. i still have a way to go but it is getting there. to start with i made a bit of a mistake and tried to power it from my two 24 volt battery chargers wired in series. that was a mistake, the voltage measured at 52v but when i switched it on it all seemed ok but then r2 (the one in the picture) started to smoke i looked at the meter quickly and shut it down, the meter was reading 72v
. (wonder why it didn't shut down from over voltage?) i hooked it up to 4 old car batteries like i should have in the first place and i fired up fine. that resistor is running warm though is that normal?. the ecore is pretty noisy but i haven't glued it yet and the transformer is making a bit of noise but i am guessing that is because it isn't epoxied, i just stripped the primary off and added 20 turns to the seccondary?
thanks for all the help it sure is good when it all starts coming together
Cheers,
Sam
