I need to make a switching power supply with a conversion frequency of about 100 kHz with a supply voltage of about 12V and a current consumption of hundreds of thousands of Amps and this is no joke. I need to use MegaJoules of energy per pulse, and the most compact solution is batteries.
I don't want to waste time, this is expensive time of my life, during which I could earn money, clean the house or prepare firewood. “Do better, the worst comes naturally” is a principle of life and I created the topic not for jokes.
My budget is limited and I need to use inexpensive mosfets connected in parallel. I need a ready-made working diagram.
100kHz, 12V, 100kA
Hi,
"Ready-made working diagram". Wow, 100kA, 100kHz, you're asking for everything and then some.
This is a problem for an experience engineer with a lot of experience in power circuit design. I've actually done this very thing for a number of years and still absorbing new ideas and techniques yet I'm not sure even I would want to attempt something like this. The issues are 100kA and 100kHz. 100kA is a lot of drain-source current, and 100kHz is a top limit for many power converters. This means you will be at the edge of some of the technologies with this. What I am saying is you need to hire an engineering firm this is not a hobby project.
You can't imagine the problems that will crop up with something like this. I'm not even sure I want to list them. There are techniques and methods that are needed to be understood fully to get something like this to work, and some of those techniques and methods would only be known by personnel that have actually worked in the power control industry for some time. This would be considered insider information; things that you never hear about unless you work in that industry and thus have no idea about as of yet. That's why you need someone who has dealt with this in detail for a number of years and has demonstrated actual success over time.
So, this should not be a question about HOW to create a circuit, it's should really be about WHO to hire. It's not just a circuit we are talking about here either. It's about a physical construction. Special attention to physical layout would be a very important point.
So, start asking about who to hire not how to make a circuit. I don't usually bet on anything, but I seriously doubt you'll ever pull this off without some serious help from people who already know all the ins and outs of a complex design like this.
I'll list a few of the problems if you really want to think about it, but I doubt it will do any good because there's almost no way you will be able to deal with them all anyway by yourself.
If I am sounding very negative about this then I feel I have done my job for today in helping others with their electrical/electronic circuits and circuit theory
