Power Factor Correction Using DCM Technique and Soft Feedback Emphasizing on Boost Converter’s Inductance Calculation

Boost converters, due to their unique structure, provide the possibility of adjusting the power factor correction (PFC). However, improper calculation of hardware parameters such as inductance and switching frequency, considering the load connected to the converter’s output, can jeopardize the converter’s performance. In other words, the converter’s operation may deviate from the Discontinuous Conduction Mode (DCM). This paper focuses on the calculation of inductance to achieve optimal performance, specifically targeting DCM operation for sinusoidal unidirectional inputs. In other words, a one-sided smoothing capacitor is not used in the output, emphasizing the PFC aspect.
