I am wondering if it is possible to use an anti-current to push the B down the curve. Let me explain.
I need a large inductance at a high current for a 60 Hz battery charger. 5
0+v at 80amps should do fine. Of course, We =LI^2 is going to determine the physical size of this unit, and it will be large. (Obviously PFC would be a natural way to go, but time is a factor. )I suppose it would be possible to inject an opposing current to push the fl ux down so that it is almost centered on the core. Would this allow me to u se a smaller core? I am also aware that you don't get something for nothin g - so I expect the pain is just moved from the inductor to the power suppl y I need to inject the counter current.
This is similar to the closed loop LEM sensors, without the large inductanc e.
Thanks Bob
