Hi everyone,
I am working on a personal project that requires me to create a power supply and charging solution at the same time and I am not really sure where to begin. For starters, the input is 400V-AC at 50Hz, about 12-13kW of power minimum. What I'd like to do is first to convert it to 24V DC, then split it seamlessly between a 24V-DC, 11kW consumer and 1-2kW, 24V-DC battery charger that can work at the same time all while trying to minimise the size of the system of course.
While I was doing the research, I was looking how typical chargers and rectifiers work, most of them increase the frequency significantly with transistors (maybe I could use an IGBT?) to reduce the size of transformers and capacitors used for smoothing but all that is for low power applications and hence hardly applicable to my situation. After quite a lot of reading I have no idea where to even start so I came here to ask you gentlemen (and possibly ladies) for advice on how to tackle this problem.
Is it possible to convert all that power to useable DC without making the system too bulky?
How would I even go about splitting those 2 outputs at the same time?
What if the input power varies from time to time (sometimes it's giving 15-16kW because of higher input voltage) but I need to limit it to 12-13kW, would I use some kind of variable resistor to dissipate the power?
