Well, that is a very nice vote of confidence thanks Poida, maybe a little premature though but time will tell. If others can get something running even half as well as KeepIS's inverter it could be regarded as a reasonable success I reckon.
One of the mantras hanging in our R&D lab many (~40) years ago was "It is easy to improve on what already exists". FET and power switching & switch-mode technology has formed a very large part of my later career. The Oztules/Mad inverter had a mixed success outcome, some you couldnt kill others you killed it randomly seemingly for no reason.
I had almost no first-hand experience with SPWM inverters but have never shied from a good challenge, this has become yet another late career change I guess, but the money sure sucks!
After you created code for my version of a sinewave converter and we tied it to the inverse opto drive system that Warpspeed promoted, I proved that an EG8010 or a Nano controller could both work very successfully with my inverse Opto buffered implementation.
So like Edison who when asked about failing to make a light globe after 100 failed prototypes replied, I have not failed, I have just learned 100 ways not to make a lamp. I also looked at what did not work and just tried to improve on it, time and feedback will be the real arbiter of success or otherwise.
I paid ~$725 for all the boards today about $166 was freight, so I hope everyone can afford them lol, there are essentially 12 takers some want 4 so it wont be too scary.
