This paper explains about basic working principles, governing equations, implementation problems, and experimental results of a new power factor correction (PFC) topology. In this proposed topology, a bridgeless boost PFC circuit based on totem-pole topology that works under interleaved critical-conduction-mode (CRM) condition is presented. The circuit was developed in order to gain fundamental understanding towards high efficiency, high performance, low-cost, simple control scheme, and low conducted electromagnetic interference (EMI) PFC circuit. The application is targeted toward middle power applications that normally employs continuous or non-bridgeless interleaved boost converter.
