A practical and integrated approach for power switching supply teaching: Example of a boost converter topology

Teaching the "electronic switching power supplies" design - like other fields of electronic- is not always easy: There is classically theoretical courses and practical lessons. The link between the two is often the most important difficulties that appear for the students. Despite a abundant literature on switching power supplies, a global and simple analysis is rarely found. In order to improve the efficiency of our teaching, we present here a practical and pedagogical approach based on Hermann modelling (including magnetic, practical considerations, design method and flowchart) for understanding and designing classical switching power supplies. It looks like a progressive linear guide from the most simple to the most difficult. A boost converter topology is used to illustrate our approach.
