CONTROL AND POWER MODULE FOR INTEGRATED ALTERNATOR-STARTER

摘要

The invention concerns a motor vehicle alternator-starter control and power module, connected between the alternator-starter (3), an on-board source (Ua) and a ground line (GND) of the vehicle, comprising: a transistor bridge with a plurality of branches (B1 B3), a control unit for comparing a phase voltage ( PHI ) of the alternator-starter with a reference voltage (Ua, GND) and control the transistors based on the result of the comparison, the control unit including: a driver (10, 20, 30) for each branch of the transistor bridge, said driver being connected proximate the transistors of the branch, and a control circuit for controlling the drivers.
