“Minimizing Penalty in Industrial Power Consumption by Using APFC unit”: A Review

The proposed device automatically corrects the power factor without any human presence. It consists of a microcontroller which detects the power factor value, if the power factor goes below 0.9(lagging) during peak hours it automatically connects capacitor banks to improve it. Now a days, one APFC panel cannot be used for different application. To make it universal we provide four keys UP, DOWN, ENTER, MENU. These keys are used to enter the capacitor values and to vary the CT ratio. As the capacitor values and current magnitude varies according to the application. The main aim of the proposed model is to maintain the power factor nearer to 0.9 which helps to increase the efficiency of the system.
