Advantages of Freewheeling Diode
- Freewheeling diode increases the load current of various circuits like chopper, inverter and rectifier circuits.
- Freewheeling diode keeps the silicon-controlled rectifiers from damage in various circuits from the maximum reverse voltage that is produced through the Inductive Load.
- The input power factor can be increased for converters or phase-controlled rectifiers.
- It maintains the average output voltage components and ripple components within the output for various circuits.
- This diode can be operated on a broad range of input voltages.
- The Flyback converters use very less components compared to the other kinds of Switched-mode power supply.
Freewheeling Diode
In an Electrical circuit, a Diode is a semiconductor device that acts like a one-way switch (it allows current to flow in one direction and restricts the current to flow in another direction). Semiconductor is made up of p-type and n-type materials. Semiconductors have conductivity between conductors and insulators. To control the Load voltage, a switching element is used to switch at a particular frequency.
A severe high voltage occurs at the time the switching element is activated due to the stored energy within the magnetic field of the inductive load coming across the switching element terminals in switch OFF condition which may destroy the switching element. To distribute this energy, a Freewheeling diode is used. The Load can be short-circuited at the time the switching element is inactivated. The energy stored in the magnetic field is degenerate like heat.
