Power losses analysis in AC/DC conversion based on active front end systems

In this paper, a methodology for power losses analysis in Active Front End (AFE) converters based on VSI has been proposed. The interest in these converters topologies in AC/DC conversion, have become more popular in recent years due to its employment in renewable energy applications. Thus, it is interesting to analyze this converters in terms of their thermal behaviors in order to evaluate the system power rate. With this work, an analytical and numerical approach for losses evaluation have been proposed by the authors. Moreover, the use of the AFE in configuration Synchronous (SAFE) has been considered and compared with the base topology.
