An interleaved PFC consists of two boost converters sharing the same load capacitor. As shown in the simplified schematic, if it is assumed that each boost converter has the same inductance, the energy stored by the system is doubled. Since the energy stored in the inductors is a key factor for determining the output power capabilities of the system, the output power provided by single stage PFC can be provided by an Interleaved PFC with much lower inductance values. Lower inductance means smaller inductors for a given power rating.
