Phred,
Do not action this artwork, it is untested, and contains errors I assure you.
I have etched the thing and noticed a few alterations I want to do, and one glaring mistake in the 2110 power lines..... and we/I still have no idea as to the dimensions of the 32 pin board width. There are also some different converter boards to fit the 8010 chip coming that are not dip32 style, and they may give a better, less inductive pathway... so hold on for a bit to avoid disappointment..... I will be disappointed enough for both of us if it does not work properly.
The original one I posted does work ( and I don't think I have made any real alterations to it... will look tomorrow), and is the current test bed, and if the new one works that well I will be ecstatic.... and it should... maybe.
It will not have the cross conduction protection transistors in stage one, as I don't think they need to be there...... and I have been wrong before too... may incorporate them if necessary.
There will not be a mud map, as I don't have one, I design on the PCB program with a few scribbles next to the computer that describe bits of it ( mainly pin out stuff), but I am not an EE so don't operate like one... I'm just a run of the mill scumbag experimenter.... having way too much fun too i might say.
When the new one works as planned, a very full explanation and drawings will be made available, as it will be ( I think) the first very simple, high powered pure sine wave inverter, that can handle all loads as easily and effectively as $8000 units can... and be freely available on the net, and so simple, that anyone with only average skill will be able to emulate simply and easily... well thats the plan anyway.
It is single sided deliberately so it is simple to make, and you will notice that most of the resistors are actually 0 ohms pieces of wire... there is not much on there.
You are more than welcome to reverse engineer it and provide the world with a mud map if you so choose.
Clockman, I have run the tests using the torroid current transformers of the type I alluded to, they work perfectly well instead of the CT shown in the pics.
