Abstract
An automotive alternator includes a stator winding that is made of a metal other than copper and copper alloys. The alternator also includes a built-in rectifier that includes a plurality of rectifying elements and a plurality of electrical conductors. The rectifying elements and the electrical conductors together form a rectification circuit for rectifying AC power output from the stator winding into DC power. Further, at least one of the electrical conductors includes first and second portions. The first portion is connected to at least one of the rectifying elements, and made of copper or a copper alloy. The second portion is connected to the stator winding, and made of a metal containing a metallic element that is also contained in the metal of which the stator winding is made.
