In systems where there is back-emf induced to oppose the applied voltage, or to change it in cases of power converters, is there a direct way to cancel back-emf or harness it back?
The simplest way to cancel back-emf to me is to increase the supplied voltage from the supply, but is there another way?
Another complicated idea to me, might be an inductor, but what if the back-emf was quite high? Use multiple inductors?
Just wanted to know the possibility.
