Bridgeless PFC - Interleaved Boost Converter with Switching Frequency Modulation (IBC-SFM)
The switching cell with switching frequency modulation (SC-SFM) has several benefits with respect to power conversion. Some of the most important features are those present in the boost variation, denominated as interleaved boost converter with switching frequency modulation (IBC-SFM). The converter conciliates some CCM characteristics, such as, continual conduction in the input inductor and limited current effort in the active components, with characteristics of some DCM converters, such as, resistive behavior for the input, soft-switching and no reverse recovery for the diodes. The IBC-SFM in the totem-pole configuration for power factor correction (PFC) is presented through a simulation file in this Dataset, operating with open-loop control.
The "IBC-SFM_Totem-Pole_PFC_Converter.psimsch" is a simulation file intended to be used with the PSIM software.
