Rectifier bridge circuit for phase voltages of motor vehicle alternator, has diode of higher temperature resistance at position in circuit where higher temperatures can occur

摘要

The rectifier bridge circuit includes a positive (2) and a negative (3) half bridge with multiple diodes (4-9). A diode (Za) of lower temperature resistance is arranged at a position in the rectifier circuit where, in operation, lower temperatures can occur, and a diode (Zb) of higher temperature resistance is arranged at a position where higher temperatures can occur.
