Researchers from North Carolina State University say they have developed a new manufacturing process and chip design for silicon carbide (SiC) power devices. The process, called PRESiCE, was developed specifcially to make it easier for companies to enter the SiC marketplace and develop new products. “PRESiCE will allow more companies to get into the SiC […]

World’s First 3D robotic LED sign brightens up Times Square
Coca-Cola recently unveiled a new six-story digital sign in Times Square featuring 1,760 independently moving LED screens, choreographed to the content on display. Coke says Guinness World Records was on hand for the sign’s debut and awarded The Coca-Cola Company two record titles: The Largest 3D Robotic Billboard and The First 3D Robotic Billboard. Few […]
Your next hotel shuttle ride could be on an EV
A zero-emissions full electric system just became available for Ford Transit passenger wagon, van, cutaway and chassis cab models. The Ford Transit wagon is a vehicle that frequently finds use in airport shuttle and similar operations. Developed by Lightning Systems in partnership with controls maker New Eagle, The LightningElectric zero-emissions package is available for Ford […]
Measuring antenna properties
An antenna is simply a conductor or conductor array, usually metal. But how it is situated and terminated that determines its behavior in transmitting and/or receiving electromagnetic radiation. Let’s start with an antenna that is configured to transmit. An oscillating voltage applied at a terminal will cause current to flow through the antenna. A transmitting […]
Learning SMPS the hard way
By Tahmid, EDAboard.com forum member SMPS is the toughest section in power electronics. For this subject, you require additional knowledge for choosing the active and passive parts used in SMPS circuits. The special type of parts often required in power electronics (i.e. for low-frequency applications) may not be suitable in the case of SMPS. When […]
Eye and Constellation Diagrams, Pt 1
Digital signals representing data symbols may be presumed to be clean, consistent representations of ones and zeroes when they are launched onto their communications medium, whether it is a wired, wireless RF, or optical fiber link. However, due to bandwidth limitations of the medium, external and internal noise, crosstalk, multipath, reflections, and many other unavoidable […]
Expanding I/O with MUX, DEMUX, and decoders
The relentless march of technological progress has given engineers increasingly smaller and more energy efficient microcontrollers to use in their designs. These benefits do come with a cost, however. Physically smaller packages have less room for I/O pins meaning fewer peripheral components can interface with the microcontroller itself. Fewer peripherals means less functionality which tends […]
Researchers say sliding-mode algorithm cleans up ripple in buck converter output
A special kind of control technique is said to be effective at eliminating voltage ripple in the output of buck converters that see a wide range of inputs. The design comes from scientists at Golestan University in Iran, Concordia University in Canada, and Delft University of Technology in the Netherlands. The researchers published their study […]
