WebApr 8, 2024 · A flyback is a simple DC-to-DC or AC-to-DC converter which consists of a transformer that stores the energy when the current is passing through the circuit and releases it when the power is removed. A flyback topology was chosen, keeping in mind its characteristics, to be used for both step-up and step-down operations. 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. ravpower iphone charger
