Can a stepper motor flyback diode discharge a coil when connected in … WebNov 24, 2016 · A flyback diode serves to protect your circuitry from this effect. Because diodes have a forward voltage well under the thousands of volts generated by the inductive spiking, the extra power from the collapsing field instead goes through the flyback diode. high school mumsThe schematic of a flyback converter can be seen in Fig. 1. It is equivalent to that of a buck-boost converter, with the inductor split to form a transformer. Therefore, the operating principle of both converters is very similar: • When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source.
