Power Factor Improvement using PIC Microcontroller

Hello friends, I hope you all are fine and good health. Today I discuss with you about Power factor improvement using PIC microcontroller. In previous post I discuss about stepper motor control using keypad all the friends likes that post and good comments so I impressive from our friends and today I have new post share with you about Power factor improvement using PIC microcontroller.

Introduction:

In this final year electronics project Power Factor Improvement using PIC Microcontroller we improve the power factor according to load. We measure the power factor using microcontroller and display the value of power factor on LCD. We measure the main AC voltage and current of load. We also use zero crossing detector circuit in power factor improvement using PIC microcontroller to check the zero level of voltage and current waveform. Different methods use in daily life for improve power factor but in this project we use a capacitor bank for improvement the power factor.

Working:

In this final year electronics project Power Factor Improvement using PIC Microcontroller. First of all we give the supply voltage all the circuit. We use potential transformer (PT) for measure the voltage and current transformer (CT) for measure the current of load and also have used to zero crossing detector circuit to check the zero level of sine wave and compare with PT and CT output wave form for measuring the power factor. Power factor measure using PIC microcontroller and display the value of voltage, current and power factor on LCD using microcontroller then we check power factor condition is lagging and leading according to load. If power factor is lagging on resistive or inductor load then check the controller and switch the capacitor through relay then power factor is leading. We have use a resistive load (Bulb), inductive load (choke) and capacitor bank in this final year electronics project Power Factor Improvement using PIC Microcontroller for improve the power factor.
