Fly back diode for ac motor

WebPreventing Flyback with Diodes To eliminate the possibility of a switching device (such as a transistor) from being damaged by inductive flyback, you can use a flyback diode. The … A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters.
