“…1) 0 (The actual value is 33 m , but is neglected to enable the simplified equations to be used); 2) 135 H (The actual value is closer to 105 H, but increased to compensate for neglected stator resistance); 3) 0.004 v-s/(rad)A , the electrical frequency of the alternator voltage is computed using r/min (14) where is the number of poles (12) and r/min is the alternator's speed in revolutions per minute (r/min); 4) 180 Hz, 600 Hz for idle (1800 r/min) and cruising (6000 r/min) speeds, respectively; 5) , the field current for this alternator (named alternator-A), is set not to exceed 3.6 amps; 6) 100 kHz (SMR switching frequency). The characteristics of the Alternator/SMR system were first investigated analytically with Matlab, using the averaged equations developed in Section II.…”

include design, manufacturing, and control techniques for power electronic systems and components, and their use in a wide range of applications. Dr. Perreault received the Richard M. Bass Outstanding Young Power Electronics Engineer Award from the IEEE Power Electronics Society and an Office of Naval Research Young Investigator Award. He is a member of Tau Beta Pi and Sigma Xi.Thomas A. Keim (M'90) received the Ph.D. degree from the Massachusetts Institute of Technology (MIT), Cambridge.Following graduation, he remained at MIT for several years as a member of the sponsored research staff, working on superconducting electric machines. He then worked for over a decade with General Electric Corporate Research and Development, where he contributed to and led work on superconducting electric machines and on superconducting electromagnets for medical nuclear magnetic resonance imaging. In his next position, he served for nearly a decade at Kaman Electromagnetics as a Corporate Officer and Chief Engineer. In this position, he led engineering of multiple high-performance electromechanical and power electronics systems, for applications ranging from military propulsion systems and launchers to traction systems for public transit to oil-drilling machinery. Since 1998, he has been with MIT, where he is a Principal Research Engineer and serves as the Director of the MIT/Industry Consortium on Advanced Automotive Electrical/Electronic Components and Systems. In this capacity, he conducts and directs research into the future of automotive electric power systems. He has authored over 34 publications and is the holder of nine patents.

“…In either case, the severity of the fault is much lower than other possible failure modes (e.g., regulator failure). We thus conclude that-to first order-designs incorporating a switched-mode rectifier can be acceptable from a reliability and fault tolerance standpoint [17]- [19].…”

Absdmct-At present most automobiles use a 12V electrical system with point-to-point wiring. The capability of this architecture in meeting the needs of future electrical loads is questionable. Furthermore, with the development of electric vehicles (EVs) there is a greater need for a better architecture. In this paper we outline the limitations of the conventional architecture and identify alternatives. We also present a multi-attribute trade-off methodology which compares these alternatives, and identifies a set of Pa7.eto optimal architectures. The system attributes traded off are cost, weight, losses and probability of failure. These are calculated by a computer program that has built-in component attribute models. System attributes of a few dozen architectures are also reported and the results analyzed.
