Master's Thesis TUM: Reduction of Transient Disturbances within Automotive Energy Systems through Adjusting the Dimensioning of Distributed Systems
This contribution should examine a methodology for the optimized dimensioning of input circuitries of low-voltage components regarding a reduction of load transients and voltage perturbations. The optimization concept should be confirmed by means of simulation.
Keywords: optimization, automotive, energy system, driverless, automated driving, input circuitry
Dynamic and safety-relevant electrical components in automotive energy systems increase the functional requirements to the energy and power supply. A reduced availability of energy or power within energy systems of self-driving vehicles is particularly safety-critical.
Elevated power peaks could damage electrical components, reduce their performance, lead to malfunctions or impair the energy systems stability.
Automotive energy systems without additional low-voltage storages use distributed capacities in form of input circuitries as power reserve for transient processes (switching processes, mechanical or electrical load fluctuations). Power peaks of 12V components need to be balanced quickly through the DC/DC converter or distributed capacities. This contribution should examine a methodology for the optimized dimensioning of input circuitries of low-voltage components regarding a reduction of load transients and voltage perturbations. The optimization concept should be confirmed by means of simulation.
