Experimental investigation on voltage stability in vehicle power nets for power distribution management

The power demand and the complexity of vehicle power nets has increased continuously during the last years. Especially the high demands of chassis control systems can cause voltage drops that endanger the power net's stability. A power net test bench that enables experimental research on voltage stability in vehicular power nets is presented in this paper. Thereby the relevance of voltage stability issues in today's and future vehicles was analyzed. Furthermore, proposals on counteractions using a power distribution management system are pointed out and the possibility of verifying dynamic power net simulation tools is provided.
