This Project Report On Control Of Dc Fan is about the DC fan and its control, the report provides the detailed explanation of DC fan, its use and how DC fan work. The aim of the project DC fan is to control a 12V DC fan using a power electronic circuit works on the operation of Thermistor. A rectified 12V DC input is given to the circuit which contains an arrangement of Thermistor, Relay, Potentiometer and various other electronic components like Diode, Transistor and Resistors.
The operation of 12 volt DC cooling fans typically used to supply cooling air to electronic equipment: These fans are typically based on two-phase Brushless DC (BLDC) motors drawing between 1 and 50 watts of power. Single-phase brushless DC motors are also used in fans, but this is outside the scope of this application note.
The report also contains the details of Thermistor. Thermistor are widely used as inrush current limiters, temperature sensors, self-resetting over current protectors, and self-regulating heating elements.
There nine elements are available in this report that are explain how the DC fan words. The elements are Theory of Operation, Thermistor, Transformer, DIODE, Variable Resistors, Rectifier, Light-emitting diode (LED), Relay.
If 230V input voltage of the transformer is given, then we get 12V output supply of the secondary terminals, the output voltage of the rectifier circuit is applied, and it directs the 12-volt alternating current into direct current and the rectified voltage is working on the application main circuit and our circuit and is controlled by the change of temperature thermistor signal to the internal circuitry and the fan speed.
Project Report On Control Of Dc Fan Conclusion:
In the future, this type of circuit can be used for the design of smart-house concept by various other sensors. This circuit can also continue to vary for the design temperature measurement fan whose speed is implemented as per the requirement of people.
