The load with a poor power factor speeds up the flow of electrons when compared to the load with high power factor in the electrical power systems. The current extracted from the system is distorted by non-linear loads. In this paper, to achieve active power factor correction Boost converter topology is utilized. The boost converter topology must meet two concurrent conditions:1) the boost converter’s input value must be set lesser than the output voltage value and 2) the voltage at any point of time must be set in such a way that it is always proportional to the current. This scheme utilizes a positive output luo converter which is connected to rectifier circuit to offset the harmonic current from the rectifier. This paper presents a new control scheme to accomplish a power factor closer to unity.
