The paper is intended to introduce power conversion principles and to define
common terms in the domain. The concepts of sources and switches are defined
and classified. From the basic laws of source interconnections, a generic
method of power converter synthesis is presented. Some examples illustrate this
systematic method. Finally, the commutation cell and soft commutation are
introduced and discussed.Comment: 29 pages, contribution to the 2014 CAS - CERN Accelerator School:
