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.
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
