Contributions to the theory and design of a D.C. buck converter used in electrical system of automotive 2000-05-0032
In papers are presented the structure and particularities of D.C. buck converter which can be used in the electric system of automotive. The equivalent circuits of buck converter deduced by energetically reasons and analysis of the power transfer through this converter is presented. To the analysis of the power transfer are done considering three sorts of load resistive, resistive inductive, and resistive capacitive load. Analyzed are the dependence of power transfer Vs switching frequency and duty factor. In the final part of the papers are presented graphics obtained by calculus.
