Abstract
An aspect of the present disclosure provides a bus bar as a winding in a core of a transformer includes multiple sub-bars arranged horizontally and connected in parallel so as to minimize an AC current in the transformer, and the sub-bars have different widths and thus resistances or impedances with respect to a current flowing through the sub-bars are the same. Another aspect of the present disclosure provides a method of designing a bus bar for resistance or impedance matching between multiple sub-bars included in the bus bar to share a current to minimize an AC current in the transformer. Another aspect of the present disclosure provides a transformer, for a DC-DC converter for use in a vehicle, which is manufactured by the method of designing a bus bar.
