Circuit Schematic Fan Voltage Regulator using TRIAC,DIAC

Robometricschool. - Here is circuit schematic of  Circuit Schematic Fan Voltage Regulator using TRIAC,DIAC like in figure 1 below. With this article we will give you global description about this electronic circuit schematic and also some component parts of this  Circuit Schematic Fan Voltage Regulator using TRIAC,DIAC.

Circuit Schematics

Component Parts
  1. Resistor R1 – 10 K ohm
  2. Variable resistance or potentiometer R2 – 100 K ohm
  3. Polyester capacitor C1 – 0.1 µ F (For operating range of 500 V or above)
  4. DIAC, D1 – DB2
  5. TRIAC, T1 – BT136
  6. A single phase ceiling fan or AC motor – 220 V, 50 Hz (ranges below 200 Watts)

Electronic circuit schematic like in figure 1 above is  Circuit Schematic Fan Voltage Regulator using TRIAC,DIAC. Due to the advancement in power electronic technology, the alternative design of fan regulator (voltage regulator) can be easily implemented to reduce the energy losses that are caused by conventional voltage regulators. This type of voltage regulator is an energy saving device which uses TRIAC, DIAC and potentiometric resistance.

This method provides the step less control of the fan speed by deriving the required amount of power from the main supply at a given instant .Hence the power is conserved rather than wasted unnecessarily. Let us discuss briefly about this voltage regulator circuit and its working.

Now we are going to build the voltage regulator circuit which is generally used to control the speed of the fan in our homes or offices. As we know that by varying the firing angle of the traic, the power applied through the load is controlled which is nothing but a concept of power control using TRIAC.
