Abstract
In a power supply system supplying several loads ( ) using a joint power bus (LB) and connecting electronic control units (&mgr;C) with each other and the loads by means of a control bus (CAN) for digital information and control data, a measuring resistor ( ) connected in series with the power bus measures the total current of the loads connected, measurement information is transferred on the control bus (CAN), and the differential current resulting from a switching process is evaluated by the control system. The measuring resistor ( ) comprising a metal alloy is integrated with a semiconductor chip with heat conducting connection directly or via a printed circuit board (PCB), which contains the whole evaluation and transmission electronics, into a small, compact current measuring module.
