Abstract
A vehicle AC generator having a rectifier unit with cooling plates for the positive-electrode and negative-electrode sides, each having principal planes opposing each other; and a diode package disposed between the cooling plates for the positive-electrode and negative-electrode sides. The diode package has a base for the positive-electrode side formed of a metallic plate and joined to a cathode face of the unidirectionally conducting element for the positive-electrode side; a base for the negative-electrode side formed of a metallic plate and joined to an anode face of the unidirectionally conducting element for the negative-electrode side; and an insulating resin provided so that the unidirectionally conducting elements for the positive-electrode and negative-electrode sides are embedded therein. The end face of the base for the positive-electrode side is joined to the principal plane of the cooling plate for the positive-electrode side while the end face of the base for the negative-electrode side is joined to the principal plane of the cooling plate for the negative-electrode side.
