WebMay 10, 2024 · However, the high switching stress in buck-boost converters offsets its PFC application and highlights the advantages of the PFC boost converter. Another reason to choose a PFC boost converter is the filter inductor in the input side of the boost converter topology. The inductor smoothens the continuous current and eases the filtering action. Websignals. The PFC duty cycle changes while the instantaneous line voltage changes, but the DC/DC duty cycle keeps a constant value during a line cycle. Figure 4.3 shows the example circuit of the two-stage PFC converter in this analysis. It has a CCM boost PFC converter as front-end stage and a forward converter as the DC/DC output stage. matthew iverson dla
