Alternator or alternator/starter power transistor auxiliary starter having car network feed control unit with auxiliary feed driver only passing driver current whilst network feed insufficient.

摘要

The voltage rectifier has a car network feed to an alternator (AD) with a rectifier bridge having power transistors and control units. Each control unit has a transistor (11) with a driver (DV) to an auxiliary feed (Vb). The auxiliary feed only passes current to the driver whilst the car network feed is insufficient.
