Step-up transformer and an electric apparatus using the same

摘要

PROBLEM TO BE SOLVED: To provide a set-up transformer and an electric device using the same by which the reduction of size in thickness, downsizing and cost reduction can be realized.;SOLUTION: Two core members 29 and 30 provided with a same shape and first, second and third magnetic legs arranged in order are laminated in reverse direction with each other so as to form a core, and the second bar of two core members is inserted into the cylindrical part of a bobbin which is wound by primary and secondary windings, thereby constituting a set-up transformer. Therefore, the number of core members as well as the kind of parts can be reduced, and the reduction of size in thickness, downsizing and cost reduction can be also realized.;COPYRIGHT: (C)2002,JPO
