The power-factor-correction circuit shapes the inductor current to appear as if a resistive load was connected at the output of the diode rectifier. It is false.
Power Factor Correction may be a technique that employments capacitors to decrease the receptive power component of an AC circuit to improve its efficiency and reduce current. A power factor correction (PFC) circuit is included in a control supply circuit to bring its power factor close to 1.0 or reduce harmonics. Many electronic circuits have a capacitor at the input of the control supply to function with DC voltage. This capacitor might cause a phased move between the sinusoidal AC control supply voltage and current and the control to calculate (PF) will drop. A power factor correction (PFC) circuit diminishes the harmonic twisting within the supply current and makes a current waveform near a crucial sine wave in arrange to extend the power calculation to unity.
