WebDec 10, 2024 · This diode is known as a fly-back diode or freewheeling diode. When there is a phase reversal, this diode acts as the short-circuit path for inductive load current rather than passing it through the thyristors. Hence the thyristor regains its blocking state once there is a phase reversal in the supply. ... The free-wheeling diode improves 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 … 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).
