Rectifier bridge circuit for phase voltages of motor vehicle alternator, has diodes of higher current carrying capacity in part of circuit where high temperatures prevail

摘要

The circuit has a positive half-bridge (2) with multiple positive diodes (4) and a negative half-bridge (3) with multiple negative diodes (5a,5b). An arrangement (5a,5b) of diodes having higher current carrying capacity is arranged at a position in the bridge circuit where high temperatures prevail, and an arrangement (4) of diodes of lower current carrying capacity is provided at a position where lower temperatures prevail.
