Electrical Power System Architectures for Military and Commercial Vehicular Applications

Abstract : Future military and commercial vehicular electrical system architecture proposals are presented in this paper. These are necessary to meet the growing demands of electrical loads, such as electrification of traditional mechanical loads, in-vehicle computer and multimedia systems, among others. In this paper, future electrical system architecture proposals using 42-volt dc and 120/230 volt 60 Hz ac are discussed. In many instances military can afford to develop technologies earlier than the commercial sector. Later these developments can lead to commercial applications. In addition, cost and technical issues are examined for these high voltage systems. These issues arise due to new requirements of load, battery, ignition systems, fuses, connectors, and wiring harnesses.
