STMicroelectronics' 1200V IGBT Series of power transmitters was created to reduce the environmental impact of daily-use equipment such as home appliances, HVAC systems and industrial machines. The transmitter was designed to minimize two major sources of energy loss — conducting and switching.
According to STMicro, the transmitter's lower switching losses were engineered to allow a higher operating frequency, which in turn permits smaller and lower-cost components to power-control circuits. Its compact, industry-standard TO-247 package is intended to save component count by integrating the ultra-fast freewheeling diode required by most circuits.
The IGBT was also designed to survive short circuits lasting up to 10 µsec, making them resistant to common causes of motor-controller failures such as an error in the gate drive signal, shorting at grounding and breakdown of motor phases-to-phase insulation. The goal is to improve motor reliability and save on repair and replacement costs.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
