Freewheeling Diode Benefits

This diode is known by many other names such as kickback diode snubber diode commutating diode freewheeling diode suppression diode clamp diode or catch diode. The use of free wheeling diode in a full wave rectifier reduces the harmonic effects in the circuit which is the major advantage of free wheeling diode.

Freewheeling diode benefits. A flyback diode is also called as freewheeling diode. The resistor represents the small residual resistance of the inductors. This is achieved with the use of a freewheel diode sometimes called a flywheel diode.

Freewheeling diodes are special type of diodes these are also called by many other names like snubber diode suppressor diode catch diode or clamp diode commutating diode. A flyback diode is sometimes called flywheel diode relay diode or snubber diode as a flyback diode circuit is a type of snubber circuit. Why put a diode across a relay coil.

Here catch diode is used to eliminate flyback when the abrupt voltage spike is witnessed across the inductive load when the supply current abruptly reduced. Freewheeling diode used in the power circuits which drives the inductive load. The other names of freewheeling diode are flyback diode clamp diode snubber diode suppressor diode etc.

When the power supply is connected to the relay the inductance coils voltage builds up to match that of the power source. A freewheeling diode is basically a diode connected across the inductive load terminals to prevent the development of high voltage across the switch. When the inductive circuit is switched off this diode gives a short circuit path for the flow of inductor decay current and hence dissipation of stored energy in the inductor.

The main purpose of using freewheeling or flyback diode are power factor improvement reduces ripple components etc. What are the advantages of free wheeling diodes in full wave rectifiers. Freewheeling diode is nothing but a normal pn junction diode.

It is also called by many other names like snubber diode suppressor diode catch diode or clamp diode commutating diode. It is a good practice to put free wheeling diodes with short reverse recovery time across a semiconductor switch. Here catch diode is used to eliminate flyback when the abrupt voltage sp.

Freewheeling diode working in silicon controlled rectifier circuits output load current or voltage can be varied by controlling the point in the input ac cycle at which the thyristor is turned on with the application of a suitable low power gate pulse.
