Summary:Demands for better fuel economy and more electric power are
driving cars to multiple higher voltages. In the next 10 years the
electrical systems in some luxury automobiles will be so changed as to
be almost unrecognizable. Although they will doubtless employ the old
reliable 12 V lead-acid battery, their loads will be driven by a variety
of voltages, both AC and DC, perhaps derived from a single AC
distribution network. Designers will be able to match voltages to
individual loads for best efficiency and performance-lights perhaps at 6
V AC, electronics at 5 V DC, active suspension at 350 V DC, and motors
and actuators at 42 V DC. The digital signals controlling those loads
will be carried by a separate communications network. The enabling
technology for these advances are semiconductors. The authors discuss
the future development of automobile electrical systems
