Analytical power losses model of boost rectifier

Abstract

An analytical power losses model of boost rectifier is presented in this study. A power losses model that takes into account both continuous and discontinuous current modes is derived. The analytical expressions of conduction and dynamic losses, including losses in inductor core and winding, are given. Also, equivalent input resistance, which models single-phase and three-phase rectifiers' power losses, is modelled. The model is verified through simulations and experimental measurements on single-phase boost rectifier that is used in wind turbine with permanent-magnet generator.
