Simulation of Bridgeless SEPIC Converter with Modified Switching Pulse
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 3
Abstract
In this paper, a new bridgeless single-ended primary inductance converter(SEPIC) power-factor-correction(PFC) rectifier is introduced. The proposed circuit provides lower conduction losses with reduced components simultaneously. In conventional PFC converters(continuous-conduction-mode boost converter), a voltage loop and a current loop are required for PFC.Simulation is done on bridgeless SEPIC and full bridge SEPIC and found that by working both in DCM conduction losses is less for bridgeless. In the proposed converter, the control circuit is simplified, and no current loop is required while the converter operates in discontinuous conduction mode.
