Freescale Semiconductor says it’s teaming up with Fuji Electric Systems Co. Ltd. on the development of insulated-gate bipolar transistors (IGBTs) for hybrid vehicles and electric cars. Working with Fuji, Freescale will market existing IGBTs to its automotive customers and will develop new IGBT products.
With the addition of IGBTs to its product portfolio, Freescale says it now offers all major electronic components of EVs, including microcontrollers, analog gate drivers, battery monitoring ICs, power IGBTs, simulation tools and software.
An IGBT is a high-voltage, high-current switch connected directly to an EV’s traction motor. It serves as a motor inverter switch for EV motors ranging from 20 kW to 120 kW due to its high efficiency and fast switching.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Time was when a talented driver with a manual transmission could beat any car with an automatic transmission in a straight-line race. No more, though. In tests at GM’s Milford Proving Grounds near Detroit, the 2015 Chevy Corvette Z06 equipped with an automatic has turned 0-60 mph times of 2.95 seconds, making it about a quarter of a second faster than the same vehicle with a manual trans.
If there’s a microcontroller-based Web server in your future, then you’ll want to take note of an upcoming Design News Continuing Education Center class, "How to Build An Embedded Web Server: An Embedded TCP/IP Tutorial.”
