These devices are designed for full-switching power factor correction in motor drive applications in the 3-6kW power range. The FPDB20PH60 (600V/20A), FPDB30PH60 (600V/30A), and FPDB50PH60 (600V/50A) all integrate two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor into one package measuring 44 x 26.8 mm. They are half the size of other devices, and use 40 kHz-switching operation for less power loss, typically providing 99 percent power factor. They have under-voltage and over-current protection through integrated gate-driving IC, and offer an isolation voltage rating of 2,500 Vrms/min.
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.
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.
