Hi folks, another Q on snubber circuits. Are they the same as freewheeling diode?
No. Short and sloppy: A snubber circuit converts flyback voltage spikes into heat, a freewheeling diode converts flyback voltage spikes into voltage.Bringitondown said:Hi folks, another Q on snubber circuits. Are they the same as freewheeling diode?

You are both wrong. The difference between a freewheel diode and a flyback diode is the way it is used in the circuit.meBigGuy said:My answer would be:
A freewheeling diode is one form of a snubber circuit.
Where do you get that definition from ?Windadct said: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.
A snubber circuit is an electronic circuit used to suppress voltage spikes and transients in a circuit, typically by using a combination of resistors, capacitors, and/or inductors.
A snubber circuit is necessary for capacitors because capacitors have the ability to store and release large amounts of energy quickly. Without a snubber circuit, this energy can cause voltage spikes and transients that can damage other components in the circuit.
There are three main types of snubber circuits for capacitors: RC snubber, RCD snubber, and RLC snubber. RC snubbers use a resistor and capacitor in series to suppress voltage spikes. RCD snubbers use a resistor, capacitor, and diode in series to suppress voltage spikes and prevent reverse voltage. RLC snubbers use a resistor, capacitor, and inductor in series to suppress voltage spikes and provide a more controlled discharge of energy.
The type of snubber circuit you choose will depend on the specific application and the characteristics of your capacitor. Factors to consider include the voltage rating and capacitance value of the capacitor, as well as the frequency and amplitude of the voltage spikes in the circuit. It is recommended to consult a professional or refer to a circuit design guide for assistance in choosing the appropriate snubber circuit.
Yes, snubber circuits can be used for other electronic components such as diodes and transistors to suppress voltage spikes and protect them from damage. However, the type of snubber circuit and its components may vary depending on the specific component and circuit. It is important to consult a professional or refer to a circuit design guide for proper implementation.
