Power supply device for electrical distribution of electric supply voltage from power source to electronic control units in car, has central power supply for supplying regulated voltage to electronic control units

摘要

The device (20) has a central power supply (A2) to supply, from a voltage (V1) supplied by a power source (10), a voltage (V2int) to a set (E2) of electronic control units (30). The voltage supplied by the central power supply is regulated around a set point value between a set point value of a voltage to be supplied to electronic components of the control units and a nominal face value of the voltage supplied by the power source. An electronic circuit breaker is provided for disconnecting each electronic control unit from the power source. An independent claim is also included for a car.
