CCM PFC Boost Converter Design - Mouser Electronics
www.mouser.comsome peak value typically 375V, hence; a step up converter is needed to output a dc bus voltage of 380V or more. For that reason the buck converter is eliminated, and the buck-boost converter has high switch voltage stress (Vin+Vo). Moreover, the boost converter has the filter inductor on the input side, which provides a
