In this paper, the authors present the digital simulation of single phase AC-DC bridgeless Cuk for Power Factor Correction (PFC) rectifiers. A conventional Cuk PFC rectifier suffers from high conduction losses due to presence of input rectifier bridges. Higher efficiency can be achieved by using the bridgeless Cuk topology. The conduction losses are considerably reduced due to the absence of input diode bridge and availability of only two semiconductor devices in the current flowing path during each switching cycle.
