High Step-Down Bridgeless Sepic/Cuk PFC Rectifiers With Improved Efficiency and Reduced Current Stress

In this article, two high step-down bridgeless power factor correction rectifiers based on the switched inductor network (SIN) are introduced. The proposed rectifiers employ the SIN to provide high step-down voltage gain with a higher duty cycle than the competitors. They also offer higher efficiency, lower current stress, and total peak switching device powers. A thorough and straightforward desi...
