Abstract – This paper provides a comprehensive review of
consumer. So it becomes very essential to regulate the power factor with a limit. The automatic power factor improvement device is designed in such a way that it reads the power factor from the line voltage and current, calculates the adjustment required to achieve the desired power factor, switching the batteries of capacitors connected across the load.
the recent and past development of the Automatic power factor improvement is designed to automatically improve the power factor whenever the power factor falls below a certain level. As we know, the demand for electric power is increasing day by day. Nowadays, many inductive loads are used in industry and small-scale applications. These inductive loads cause the power factor to drop and are one of the main reasons for power factor reduction in industrial applications. There is therefore a need to increase the degraded power factor. The automatic power improvement provides a solution to this problem. Due to the low power factor, there is a load on the power system and transmission lines which is unnecessary. By correcting the power factor of the power system, the efficiency of the power system can be improved. In this methodology, a power factor improvement prototype is developed using a peak microcontroller, relays, a potential transformer, a current transformer, and a zero-crossing circuit.
2. LITERATURE SURVEY The article "Power factor correction unit using 89C52" published in 2014 contains the use of the 89C52 to measure and correct the power factor. The advantage of this research was that it showed the best method to measure the power factor of the systems but the disadvantage was the increase in the response time of the microcontroller [1]. The article "Power factor correction unit using an active series of filters" contains the use of active filters for the purpose of power factor correction, which is a unique method of power factor correction. The advantage of this method was the use of active filters to improve the power factor, but the disadvantage was the use of active filters because the filters do not have sharp cutoff frequencies and there were no either using controller, the circuit was not automatic [2].

1. INTRODUCTION In the current scenario of technological revolution, power is very valuable. Industrialization mainly increases the inductive load, inductive loads affect the power factor, so the power system loses its efficiency. Some organizations develop products and carry out Research and development work in this area to improve or compensate for the power factor. Nowadays, the size of the design is getting smaller and to make this possible and make it into a product, a programmable device can be used. Whenever we think of programmable devices, embedded technology comes to the fore. Despite its ease of reliability and relatively lower cost, it has some drawbacks. The relays to be used are quite bulky and require regular maintenance. Multifunctionality is out of the question. Power factor correction is a very useful tool to improve the active power transmitted to the industrial installation. If an inductive load is connected anywhere in industrial applications, the power factor lags, when the power factor drops below a certain low level (0.97 offset), the power company charges a penalty to the respective

The article "Automatic Induction Motor Power Factor Correction Using Arduino" contains the practical realization and power factor correction through the induction motor. The advantage of this article was that it solved the problem of low power factor practically at the level of the induction motor by using it as an inductive load. The downside was that using the Arduino UNO board increased the cost of the circuit because it had to be more connected to the controller [3]. The article "Automatic power factor correction unit" published in 2016 contains the use of a precision rectifier, an EXOR gate and the use of an Arduino board as well as inductive and capacitive loads for d improvement and power factor correction. The advantage of this item is that it measures the voltage and current value and solves the power factor problem and displays the corrected value, but its disadvantage is the measurement of voltage and current
