INDUCTIVE ELECTRICAL COMPONENT WITH AUXILIARY WINDING

摘要

An electrical component (10), an electric circuit (40) with the component (10), and a method of operating the electrical circuit (40) are described. The electrical component (10) comprises at least one main winding (16, 18) comprised of a plurality of conductor wire turns wound on a bobbin (14). In order to achieve simple construction of an auxiliary winding (54), at least one turn of a conductor trace (34) is provided on a surface of the bobbin (14) forming the auxiliary winding (54). In an electrical circuit (40) an integrated circuit element (46) is supplied with electrical operating power from the auxiliary winding (34).
