The Adaptation of Existing Standard EMI Impulses to a Dual-Voltage Automotive Electrical System

Prof. W. G. Hurley, Ivan Rigney

Presently, the average electrical power demand in vehicles is about 800W. With the introduction of an increasing amount of electronic components in vehicles such as electromagnetic valve actuation, electric power steering and suspension, the average power demand could increase to 2,5kW by the year 2005. These loads cannot be powered effectively by the present 14V automotive electrical system. To meet this challenge the Consortium on Advanced Automotive Electrical/Electronic Components and Systems at the Massachusetts, Institute of Technology have agreed on a new 42V automotive electrical system. With the more and more sophisticated components being added to vehicles, there is an increasing presence of devices that are sensitive to electromagnetic interference. International organisations such as the International Standards Organisation (ISO) and the Society of Automotive Engineers (SAE) demand many tests to ensure the sufficient electromagnetic compatibility of a new device before it can be used in a vehicle. This project describes these standard tests and examines how they will be affected by the move to a 42V system.
