Freewheeling (Flyback) Diode - Electronics Coach

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 supplies and inverters. Webvia the flywheel diode again. In this case, the flywheel diode is the body diode of high-side SiC MOSFET Q2. Set the pulse width in this section as short as possible, so that the load current is kept constant as much as possible. However, an appropriate time should be secured to ensure that Q1 is turned OFF.
