In motor control applications up to 2.5 kW, International Rectifier's 600V insulated gate bipolar transistors (IGBTs) reduce power dissipation in inverters by up to 60 percent or allow up to 60 percent higher rms current. The reduced power dissipation can reduce heatsink size by 50 percent. Each of the four new products in the family is co-packaged with an ultrafast soft recovery diode. The IRGB4062DPbF has typical reverse recovery energy of 621 µJ. The combination of low collector-to-emitter saturation voltage (VCE(ON)) (1.65V typical) and total switching energy (ETS) (ETS) of the trench IGBT results in reduced power dissipation and higher power density. The lead-free and RoHS-compliant IGBTs target motion control applications with wide switching frequency range such as in air conditioner and refrigerator compressors, washing machines, industrial drives, and circulating pumps.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
