Protect USB Ports From Nefarious “USB Killers"

On 4월 11, 2018 in All, Circuit Protection, Computing, Memory, Power by Paul Pickering

USB ports supply both data communications and charging power to portable and wearable devices, so it’s become more and more critical to protect ports against abuse. Fortunately, there are design techniques that reduce power surge risks to USB ports.

Lithium, Cobalt, and Lithium-Cobalt Prices, Demand Drive EVs

On 3월 21, 2018 in All, Automotive, Power by Steven Keeping

The price of Lithium has tripled since 2016 as electric vehicle batteries compete with mobile consumer electronics for the material. But the escalating price, driven by a threat of shortage of supply, is unlikely to dampen EV demand. Cobalt, another vital ingredient of Li-ion batteries, is another matter, and researchers are working hard to find cheaper alternatives, including Lithium-cobalt.

Tax Reform Keeps the Sun Shining on Solar Energy

On 2월 28, 2018 in All, Lighting, Power by David Wagman

Inverters, connectors, and panels may be the hardware that delivers solar energy to homeowners and utility giants alike, but it’s the tax breaks that often justify installing solar energy in the first place. How will the late 2017 US tax reforms affect the solar industry as a whole?

Don’t Ignore Current Sense Resistor TCR

On 2월 14, 2018 in All, Circuit Protection, Power by Bill Schweber

Unless you are in the milliamp or microamp current range, where any self-heating is acceptably small, a responsible designer must perform an analysis of resistance change using the vendor-supplied data for the temperature coefficient of resistance (TCR).

Microgrid Vision Stalls but Smart Automation Offers Reboot

On 2월 12, 2018 in All, Power by Steven Keeping

Microgrids are the key to integrating green energy. But engineers must embrace smart grid technologies before the hype becomes reality.

Tech Scores a TD at Super Bowl LII

On 2월 2, 2018 in All, Computing, Lighting, Power, RF, Security, Wireless by Barry Manz

Super Bowl LII fans in the stands will expect flawless cellular and Wi-Fi performance, and viewers at home will expect multi-view, action-packed, real-time coverage. The mammoth technology infrastructure supporting Super Bowl LII should deliver on both.

Using Logic to Understand Programmable Logic Devices

On 1월 26, 2018 in All, Automation, Dev Tools, Industrial, Memory, Power by Paul Golata

Like human minds, computing devices require logic to process information. Programmable logic devices (PLDs) follow a specific set of instructions to control, compute, store, manage, and manipulate electronic information. Several categories of PLDs exist, providing design flexibility.

Which Hardware in the Loop (HITL) Scenario Works for You?

On 1월 12, 2018 in Automation, Automotive, Dev Tools, Industrial, Medical, Power, Robotics by Bill Schweber

Hardware in the Loop (HITL) is the only practical way to test complex system hardware and software, and two ways of implementing it exist. Each approach has pros and cons, but in either case, developing the HITL installation can be a task as large as developing the system itself.

Making Mathematical Sense of PID Controllers

On 12월 8, 2017 in All, Automation, Industrial, IoT, Maker, Power by Mike Parks

PID controllers are a popular method for including a feedback as a mechanism to help efficiently control industrial processes. Short for “proportional, integrative, derivative,” PID controllers keep the output of a system constant based on user provided setpoint. Tuning the PID controller parameters, though, requires a bit of math to maximize efficiency and minimize adjustments and corrections based on feedback.

USB 3.2 Doubles Type-C Cable Speed, Adds To Naming Confusion

On 9월 27, 2017 in All, Connectors, Power by Lynnette Reese

Scheduled to release any day now, the anticipated USB 3.2 spec will double the number of lanes for data transfer and enable full-featured cables to transfer data at 2Gbps. This blog explores the new spec and clarifies the often-confusing USB features and package labels.
