Buck–Boost Common Ground Bridgeless PFC (CGBPFC) Rectifies With Positive/Negative Output

This article proposes new common ground bridgeless power factor correction rectifiers suitable for use in any application which requires a positive or negative dc power supply. The main advantage of the proposed rectifiers, compared to previous works, is the provision of the common ground between input and output, which eliminates electromagnetic interference (EMI) associated with high rates of ch...
