An overview of chopper topologies

Power electronics, which should be called “electronic energy conversion”, is now undergoing a major evolution. During these years, the size, weight and cost of converters have only decreased, largely due to advances in electronic switches. It is interesting to compare the various possibilities for achieving a converter. Some topologies will be more suited than others to a given specification. The evolution of structures is conditioned by determining factors such as performance, reliability, integration, mass and cost.in this paper; we will be interested in DC/DC converters (choppers). This paper provides general comparisons for various types of choppers and their suitable applications with useful references.
