An Interleaved Totem-Pole Power Factor Correction Converter

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