Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

These two pictures were taken at the same time with everything exactly the same, except the second picture has drive to the number four inverter plugged in.




Cheers, Tony.

OK here it is with all 4 hooked up.
It's still being fed by the restricted power supply.

I'll try it without the resistor on the supply next, then add capacitors.

To tie it in with neutral on the house I'll have to get another big plug that goes into the change over circuit.

Here it is without the resistor on the power supply. It's just being fed by a wire I got from an extension chord, so it's not capable of a really solid supply.

Next test will be to give it full power from the big battery, then add caps.

That will have to wait for another day.

Excellent progress Mark, very nice indeed !

All that furry stuff should go away, and quite probably those spikes as well, when you remove the resistor from the dc supply, and put the electrolytics back.

You can see a very nice clean sine wave hiding beneath all the fluff.
All your small steps appear to line up perfectly which means your transformer voltages (and turns counts) are spot on perfect.
Cheers, Tony.

Plug finally came from Czeck land.

Now I can hook it up and test it properly.
