Design of Dual-Output Alternators With Switched-Mode Rectification

Abstract

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.

Optimization Approaches and Techniques for Automotive Alternators: Review Study

“…Hassan, Perreault, and Keim, 2005, [48] Dual output SMR Results indicated a good response and performance for the proposed combination. Slandered Lundell alternator (14-V 65/130 A) is used in this work.…”

“…Figure 38 illustrates the block diagram for the proposed control strategy with the active rectifier. Power electronic is used again in [48] to produce a dual output voltage for the automotive alternator. The authors used SMRs to produce 42-volt and 14-volt outputs from the alternator.…”

Design and Evaluation of a 42-V Automotive Alternator With Integrated Switched-Mode Rectifier

“…A four-cell system was implemented having four separate sets of three-phase windings. Because our design incorporates a boost rectifier, the same number of turns (in each phase set) as the original 14-V alternator was used for 42-V output (see [10], [16], and [25] for the impact of turns count). The machine was rewound with each phase conductor comprising one strand of 17 1 2 -AWG wire, yielding a copper packing factor close to that of the original machine.…”

Hysteretic current controlled ZVS dc/dc converter for automobiles

“…The use of switched mode rectification (SMR) to obtain the two voltages is investigated in [2,3]. This solution offers a number of both technological and economic advantages, which seem to confirm its future applications.…”
