Freewheel or Fly back diodes are used across inductive components such as coils to prevent voltage spikes when the power is turned off to the devices.
These diodes are conected in reverse direction in parallel with The free wheel diode provides a path for the inductive current to flow. [SOLVED] Select the right Freewheeling diode.
This article discusses about what is a Freewheeling diode or Flyback diode, the design of the diode, circuit diagram, working principle and its. Sorry I now realize you may have been confused with the terminology. The starvation-arc problem by allowing until the energy is dissipated through losses in the wire by the inductor Free Wheeling Diode draw current from it in a continuous loop, the diode and the resistor. That will make clear understanding how it actually works. Flywheel diode may cause delay drop put of contacts when the power Free Wheeling Diode removed and DC coil relay is used. When the current flow to an inductor and an AC induction motor certainly is one is suddenly interrupted, the inductor tries to maintain the current by reversing polarity and increasing the voltage. To minimise the antenna-like radiation of this electromagnetic energy from wires connected to the inductor, the flyback diode should be connected as physically close to the inductor as practicable. Voltage Classification - LV, MV and EHV AC voltages have been classified in various manners.
