WebAnswer: Free wheeling diode it is a diode which is use to eliminate the flyback voltage, i.e., when the spike of the voltage come across the inductive load when their is a sudden increase in the input current. The … 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 ...
