Hi
I need some help about switching regulators step up fig 23-33b I am not fully sure about the text quoted that says
" when the transistor suddenly cuts off, the magnetic field around the coil collapses and induces a large voltage across the coil of opposite polarity. This keeps the current flowing in the same direction. Further more, inductive kickback voltage(I think back emf) is larger than the input voltage"
Kindly can someone explain for me the quoted text for me especially the bolded text?
again thanks
