Jesus you guys are nit-picky, I have experience enough, its a proposal, and not a single answer given.
Thank you very much on your judgement, now I am fully aware of the situation and the risks involved, just as I was before I posted here, risks that are certainly not parts seared in walls (I see you don't know so much if you say that can happen, because the energy needed to put anything in armed concrete far exceeds my home's power supply or the projects capacity without protection engaging first). I am not a kid, this is a uni project. I will not kill myself or blow anything up despite my funny nick from early gaming days. So if you want to give some constructive comment, do it, if not then get off my thread, because I don't like people that can't be bothered to understand, talking about expert advice (that I AM ASKING for) and Darwin awards. It was a simple question, and I gave enough information for a normal person to answer. And I know what are reactive volt amperes, volt amperes, watts,and where they are used, you missed the point, and underestimated me, probably because of my style. In the datasheet the Vss is recommended 600V and thats all the information on high side voltage sense Klaus, It has internal level shifter for gates, but it dosen't say how low can it go on the high side, only how high. My question was can it go from 0-400. I don't have a variac, and using motors to turn variacs seems bronze ageish to me, and too slow for PID current regulation(I have a reason why I said current and not voltage), anyway thanks paul for you were the most reasonable here. Google anything about variable input inverters or gate driving, information is vague, and they didn't teach us at school. So all I have is to figure it all out myself. Instead of finding more excuses not to think, lets get back to the topic:
using a DC/DC converter to vary supply voltage to the variable input Inverter.
its like a very standard buck boost system, but in reverse to regulate rail voltage from 0-needed.
so I can feed it to inverter that will output to a 220V primary of the transformer, and then I pick up its output current on secondary with a Hall probe, so it can be regulated with Arduino that operates the said converter. Do I need to translate this from human that helps me think, into engineering language first?
Do you need a schematic or a block diagram(that I already did in a way), or parts manifesto, or for me to post on this forum for 2 years to get more status? or what, for you to understand this idea? All options of implementation are still open. I will draw it for you but I thought it is a simple concept to understand, and you can help me think.
specifically I asked you about DC rail capacitor placement, and the gate driving method for full H-bridge so it can take full variable input (I think gate transformers would be ok, but i would like to keep my IC if possible). If you know of any complications this system would have, and so on...
Has nobody ever done, or try this? ? ? ? Then either tell me why, or think for a minute, or don't comment, else you might embarrass yourselves, like me apparently. But it says project guidance, my project is a concept at this point and I need some guidance because its very complicated, even at this point. If I knew everything about electronics I would not ask. How exactly am I not reasonable here? Can't we have an open-minded, good intentions conversation?
It sure will require experimentation. I charred components in projects before, and will probably char more while doing it myself with or without you guys, it happens but you can maybe help me prevent some of it. I just thought this might interest someone that knows a lot on inverters and reactive power, that can actually help me, and wont just criticize everything just to appear smarter, that I can also accredit in the damn paper. I will do all the work, and code, no complete solution is required, just opinions on the things I actually asked, twice now. Thank you
I will post more once I get to the next stage alone it seems.
