Witryna26 sie 2015 · A free wheeling diode is used in converter circuits . It is connected across the load. During positive cycle of input it is reverse biased. During negative cycle of input the diode conducts and the energy stored in the circuit inductor during the previous half cycle is delivered to the load itself. Hence average power delivered to the load ... Witryna10 gru 2024 · 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 load current waveform and increases the input power factor.
