Abstract

In the present industrial revolution, power is incredibly precious. The power quality of the AC system has become an unbelievable worry because of the quickly expanded utilization of inductive loads. The electrical energy is wasted because of the lagging power factor in the inductive loads of that client's utilization. Subsequently, there is a dire have to evade this wastage of energy, lower power figures end in poor unwavering quality, wellbeing issues, and high energy cost. The power factor of the power system is consistently changing because of the contrasts within the size and number of the loads being utilized at once. This makes it trying to regulate the inductive and capacitive loads consistently. Many control techniques for the Power Factor Correction (PFC) were proposed. This paper presents a computationally precise method to plan and improvement of a single-phase power factor correction using Arduino Nano miniaturized scale controlling chip. The hardware execution was made by using Arduino Nano board, which uses the ATmega328 as the Microcontroller, the proposed structure has the skill to identify power factor viably and by using an appropriate methodology enough capacitors are turned on to remunerate the reactive power factor, along these lines pull back power factor close to unity accordingly procures higher effectiveness and better quality AC output. In this proposition, there is a detail of plan and advancement of microcontroller-based programmed single-phase power factor revision alongside a correction circuit to actuate the transfers when the power factor cannot be redressed. This thesis revolves around the measurement of power factor using microcontroller and afterward using an appropriate calculation to turn on and off the capacitor bank to accomplish the nominal power factor specified by the loads.
