High Voltage Auto Systems Coming to a Car Near You

12 V electrical systems in your car are about to become a thing of the past. With many of the typical car's systems being slated for electrification, the planned 42 V architecture is needed for ruggedness and efficiency. Drive-by-wire steering and braking, transmission clutches, variable valve timing, and active suspensions are among the items on the drawing board now. Exotic schemes are envisioned such as stopping the engine at stop lights or stop signs, then instantly restarting when the gas pedal is pushed (lower emissions than idling). Higher voltages mean smaller gauges for the hundreds of feet of wiring in cars, which means less weight, smaller connectors, etc. Analog Devices, Infineon, and Motorola are among the companies introducing new qualified devices into the market. I wonder if these cars will qualify as hybrids?

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
