What are the advantages of free wheeling diodes in full

WitrynaForward-biased diodes are not perfectly conductive; there is a voltage drop of 0.7V (0.3V for Schottky) across them. At high currents, this results in high power dissipation across the diode. High-current diodes may have longer recovery time too. When the lower MOSFET is on, current flows through it rather than the body diode. 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.
