Abstract: To overcome the problems of power factor, a new single-phase ac dc PFC bridgeless rectifier at low input voltage is introduced. Only two semiconductor switches are used because of the absence of an input bridge rectifier in the proposed rectifier. Hence, the current flowing path during each switching cycle result in less conduction losses compared to the conventional full bridge topology. The proposed topology operates in discontinuous conduction mode (DCM). The DCM operation has advantage of simple control circuitry. The proposed topology is compared with bridged full-bridge SEPIC rectifier in terms of the power factor. MATLAB simulation has been done.
