Abstract :
The analytical expressions for boost converter loss are presented in this paper. All significant sources of conduction and dynamic losses within the converter elements, including losses in choke magnetic material and switching losses which occur due to diode recovery time, are discussed. Sources of losses in continuous and discontinuous current mode of converter are examined. The equivalent input resistance of the generator is included in converter loss model. In the paper, the case when single-phase rectifier is input circuit of the converter is presented. Loss model of converter and its efficiency was compared with experimental measurements on a prototype of the boost converter.
