Dynamic System Interaction in the 42 V Power Network 2000-01-C082

New high-power loads like Electromagnetic Valve Train (EVT) or "X-by-wire'' systems are the driving forces for the introduction of the 42 V Power Network. These systems show high average power consumption and can cause extreme power transients, which result into a substantial variation of the supply voltage. Such distortions deteriorate the performance of the individual electrical and electronic systems in the car and can stimulate critical interactions between them. An analysis of the system units and the complete network, based on simulations and measurements, must ensure the functionality under all operating conditions. This analysis was performed for a system containing an EVT system, a crankshaft starter-generator, a 36 V battery and an additional energy storage element, together with the wiring harness, and further electrical loads. The method could be applied for the design and optimization of a sensorless EVT control unit and the definition of the associated power management strategies.
