A Bridgeless Cuk-Derived Voltage Doubler-Based Power Factor Correction Rectifier

This research proposes a bridge-less (BL) Cuk converter cell derived power factor correction (PFC) voltage doubler rectifier (VDR). The proposed BL-PFC VDR employs two Cuk converter cells. The inputs of Cuk cells are connected in parallel, and the outputs are connected in series. Thus, makes the voltage gain twice. Compared to a classical Boost BL-PFC rectifier, the proposed rectifier either lowers the voltage burden on the switches or twice the output voltage gain. Since each Cuk cell works for a alternative half cycle, this VDR provides better thermal management. The proposed Cuk VDR employs an affordable single voltage sensor based voltage control method. Further, the rectifier is intended to operate in discontinuous inductor current mode for improved power quality operation. In addition, the steady-state analysis of the proposed Cuk VDR, as well as its design, and small signal analysis are detailed thoroughly. A 1 kW experimental prototype is developed to validate the performance of proposed Cuk VDR. Furthermore, its effectiveness has been validated using analytical outcomes.
