Lifer, if you think your design is solid, then you should put it out there and help people, and do a better job than me... and thats easily done.
As it is, all your research, and scrivenings will die with you... big woop.
Not everyone lives in first world countries, and would appreciate open honest work that may help their every day lives.
The open source thing is for others to ponder, I just put my work out there, with all the pimples and bruises, warts and all, tell what I know, how i have done it, and no-one has helped me to be any wiser.... thats the calibre of the other knowledgeable folks out there... a big fat zero.... and your just another one until you prove me otherwise. I welcome you to pick it to bits, advise where it could be made better.... put your better deign out there, and help the other folk to improve their lot.... I don't expect it to happen, as selfishness seems to be the order of the day with most people.
This site was made possible by the selfless experiments of the Dans. They did plenty wrong for plenty of time. Great people like Flux and Zubbly contributed to their knowledge, as well as the best teacher of all experience... they are now world wide acknowledged as leaders in this field... even if I don't agree with the Hugh piggot/ Danb mills as the best long term... I think that prize goes to Zubbly.
I built a few of theirs, and they did what they claimed ( better in fact ), but my marine environment made the neo's die fast, and the furling was difficult to control in some wind regimes. The back MMF protection of the zubbly made it near bullet proof, at the expense of output perhaps, but the best in my..... thats my book.
These little 002 units seem indestructible so far, and it is not that I haven't tried.
I do understand the gate capacitance as it pertains to oxide thickness, and surface are, and low Rds units have bigger surface area and so bigger capacitance to over come if you need to switch quickly. ... maybe even thinner oxide in the low voltage variants....who knows.. not me.
The 002's are running at 300ns dead time, which seems to cause no conduction issues or at the other end, heat and excessive waveform distortion. Lower resistance was chosen to increase the current to the gates, as the 6x 4110 has about 6n of capacitance to drive into ... lower impedance means faster turn on times, the diode to help decrease turn off time.
Interestingly it does not matter really what the theory might actually be, practice says 47r runs hot 5r runs cool.. why it does is of no importance, and you don't need to test to destruction to find out either. kiss works.
So carefully thought out does not necessarily mean better or worse, but if it works to expectations, then I don't care if I followed your example, or went my own idiotic way, the result is a unit equal or better than other units I have to fix for other people with name brand goodies.... They can't drive anything I cant, and I can drive a lot of things they cant...and for longer periods. ie I can start 10hp three phase motors for phase generators to drive 50 ton presses.. theirs cant stand the start up because of the programming probably, but the reason is mute... they can't do it... I can
I don't need to know any more than that.
I have never pretended or expressed that what I do is open source, thats for other folks to ascribe words to, read any or all of my stuff.. I don't recall ever mentioning it... but what I do is open for all or anyone to use or modify at their leisure.
I am happy that clockman and many others now have had great success using what I have done to further their pursuit of useful power.... no one has used yours from the sounds of it but you.... and your happy with that...... your loss as a human being not mine.
I had intended to use the 8010 chip with a triple isolated pwm supply, and drive optos, but have not moved forward with that one as I was pleasantly surprised that the 2110 can drive the 6 fets very very well, which I had not expected... provided I dropped the gate resistance.
You can laugh at this one too.. I know the PWM part works fine as I used that for a three phase BLDC driver for solar pumping I did a neighbour...... never went on with it though.
I will end with this... if your not prepared to help then go away from this thread, and grizzle to someone who cares.... or you can pitch in with sensible critique... there is no middle ground.

Edit Saw your last post... Yes, Andrew did do a piece on energy matters. Thankfully I did not see that or I would have ended up with a less useful device. He calculated the inductances to use that would mitigate the idle current issue.
In fact he was wrong. The inductance was way too high, as his friend found out after reading my saga with it. He ended up using mine instead.
Had I seen Andrews, I would have made the same mistake/s I guess. His filter caps were wrongly ascribed as current hogs to. The originals were just fine.
And who in their right mind would want to replicate SMA.
