ALTERNATOR HAVING SYNCHRONOUS RECTIFICATION FOR A MOTOR VEHICLE, PROVIDED WITH ELECTRONIC DEFECT MANAGEMENT MEANS

摘要

The alternator according to the invention includes a stator (s), a rotor (R), synchronous rectification means (20, 21) for rectifying AC voltages (j1, j2, j3) supplied by the stator into DC voltage (B+), and voltage-controlling means (3) for controlling the DC voltage. According to the invention, the alternator also includes defect detection means (211, 22) for detecting defects (DEF) in the synchronous rectification means (2) and for providing defect detection information (DEF) to the voltage-controlling means (3). According to another feature, means (211) are provided for storing the information (DEF) on the detected defects and/or for transmitting same to an electronic control unit (4) of the vehicle. (Refer to figure 1).
