Electromagnetic Components in Dual Voltage Systems

This paper discusses design and testing of a regulated dual voltage automotive electrical system that provides both 48 and 12 volt subsystems. The paper focuses on the design, performance, and manufacturing differences between 12 volt and 48 volt electromagnetic components for vehicle applications.

Dual voltage systems have inherent benefits of lower current consumption, smaller/lighter wiring harnesses, and potential improvement in system efficiencies. These benefits help some automotive operations, but are not readily transferred to the electromagnetic product arena.
