Jul 9, 2021 · In this topic, you study Freewheeling Diode – Definition, Diagram, Working & Advantages. A freewheeling diode is used to make load current continuous and stops the output voltage from going negative. A freewheeling diode is commonly known as commutating diode (or flywheel diode or bypass diode).
Definition: Freewheeling diode is used to protect the circuit from unusual damage caused due to abrupt reduction in the current flowing through the circuit. It is also known as Flyback diode and forms connection across the inductor to remove Flyback voltage generated across it.
This diode is known by many other names, such as snubber diode, commutating diode, freewheeling diode, flywheel diode, suppressor diode, clamp diode, or catch diode.
Freewheel diode or Flyback diodes are basically connected across inductive coils to prevent from voltage spikes in case of power getting turned off to the devices. There will sharp voltage spike when power to inductive load, i.e. coils and other inductors are turned off.
Oct 3, 2018 · What is Freewheling Diode? 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 ...
Sep 5, 2021 · A freewheeling diode is connected in motor control circuits across the terminals of the motor to let for energy dissipation stored in motor inductance to give continuity of motor current once the silicon-controlled rectifiers are blocked. This diode also gives protection against high voltages.
The freewheeling diode, also known as a suppressor diode, catch diode, snubber diode, or flyback diode, is used to eliminate a sudden voltage spike across an inductive load when its supply voltage is abruptly removed or reduced.
