What is the purpose of using MOSFET instead of free-wheeling diode …

WitrynaThe "body diode" of a MOSFET is the P-N junction between the drain terminal and the substrate. It passes current whenever the source is more positive than the drain (in an N-channel MOSFET) because … 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. rice new world or old worldWitrynaFig.8 Converter with free-wheeling diode When the feed voltage crosses the zero, the free-wheeling diode V F continuously conducts the inductive current without return of energy into ac supply and fixes the load negative voltage at about 1V until the magnetic energy stored in the inductance has been discharged with time constant = L/R. rice new student checklist
