Active power factor correction (PFC) refers to the method of increasing power factor (PF) by using active electronic circuits with feedback that control the shape of the drawn current. There are many commercial PFC controllers that can accomplish this task. In the operation of an active power factor correction circuit (Figure 3b), the incoming line voltage passes As a result, power-factor correction has become a very significant issue, leading to the creation of regulatory standards. Thanks to those standards, design/application engineers are using the latest technologies in passive and active components and controller integrated circuits (ICs) to create a wide range of power-factor correctors.
