Freewheeling Diode Purpose

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. It is also called by many other names like snubber diode suppressor diode catch diode or clamp diode commutating diode.

What is freewheeling diode and what is its purpose.

Freewheeling diode purpose. In my practice i place the flyback diodes as close as possible to the relay. For detail please visit https. This diode is known by many other names such as kickback diode.

Flyback diode is used across inductive load basically sometimes called a snubber diode freewheeling diode suppressor diode or catch diode is a diode used to eliminate flyback the sudden voltage spike seen across an inductive load when its supply voltage is suddenly reduced or removed. A typical 1n4007 diode serves me well in most applications and it saves me from the problem of having to manually create footprints. Purpose of freewheeling diode the main purpose of freewheeling or flyback diode is to free wheel the stored energy in inductor by providing a short circuit path.

The absence of a flyback diode can be your electrical nightmare. The main purpose of freewheeling diode is to provide a path for decay of current through an inductive load when switch is put off. A flyback diode is also called as freewheeling diode.

A flyback diode is a 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. Freewheeling diode is nothing but a normal pn junction diode.

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. 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.

It is also known as flyback diode. This is necessary else a sudden decay in circuit current will give rise to high voltage across the switch contacts and diode. The main purpose of using freewheeling or flyback diode are power factor improvement reduces ripple components etc.
