Modeling and Control of Single Switch Bridgeless SEPIC PFC Converter
Due to increasing concerns on the power quality, power factor correction (PFC) has become an important issue in light-emitting diode (LED) lighting applications. A boost converter is one of the most well-known PFC topologies, due to its simple circuitry, simple control scheme and small number of passive components. Even though a boost converter is recognized as a typical PFC converter, its outp...
متن کاملHigh Efficiency Bridgeless Sepic Rectifier for Power Factor Correction
A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on sepic topology is proposed for high voltage battery charger application. The proposed topology consists of common input stage and parallel output stages. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as cl...

15 صفحه اولSimulation of Closed Loop Controlled Bridgeless Pfc Boost Converter
Conventional boost PFC converter suffers from the high conduction loss in the input rectifier-bridge. Higher efficiency can be achieved by using the bridgeless boost topology. In this paper, digital simulation of bridgeless PFC boost rectifiers, also called dual boost PFC rectifiers, is presented. Performance comparison between the conventional PFC boost rectifier and the bridgeless PFC boost r...
