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 … See more Fig. 1 shows an inductor connected to a battery - a constant voltage source. The resistor represents the small residual resistance of the inductor's wire windings. When the switch is closed, the voltage from the battery is … See more When used with a DC coil relay, a flyback diode can cause delayed drop-out of the contacts when power is removed, due to the continued … See more Flyback diodes are commonly used when inductive loads are switched off by semiconductor devices: in relay drivers, H-bridge motor drivers, and so on. A switched-mode power supply also exploits this effect, but the energy is not dissipated to heat and instead … See more • Ott, Henry (1988). Noise Reduction Techniques in Electronic Systems (2nd ed.). Wiley. ISBN 978-0471850687. See more According to Faraday's law of induction, if the current through an inductance changes, this inductance induces a voltage so the current will go on flowing as long as there is energy in the magnetic field.
