Hi folks, another Q on snubber circuits. Are they the same as freewheeling diode?
a freewheeling diode converts flyback voltage spikes into voltage.
No. Short and sloppy: A snubber circuit converts flyback voltage spikes into heat, a freewheeling diode converts flyback voltage spikes into voltage.
You are both wrong. The difference between a freewheel diode and a flyback diode is the way it is used in the circuit.My answer would be:
A freewheeling diode is one form of a snubber circuit.
Where do you get that definition from ?A freewheeling diode is applied to a circuit with some (or some expected) inductance, it provides a CURRENT path to prevent significant overvoltage due to V=dI/dt. The current can free-wheel (circulate) back to the inductance.
