Increased Power Delivery Takes PoE into New Markets

On March 4, 2020 in All, Power by Robert Huntley

Looking to incorporate Power over Ethernet into your next design? Learn the specifics behind the new 802.3bt 90W power sourcing and power delivery standard and how the standard has evolved to answer the power requirement needs of today’s smart building applications.

What We Learned About EV Range Anxiety

On February 28, 2020 in All, Automotive, Connectors, General, Motor Control, Power by Tommy Cummings

We just endured the biggest adventure of our Tesla commitment ... a long-distance journey, an 853km (530-mile) roundtrip in an EV equipped with a 50kW battery that has a 362km (225-mile) range between full charges. We learned valuable lessons, and we’re hopeful for progress.

Nanotechnology Is Inspiring Next-Gen Batteries

On February 20, 2020 in All, Automotive, Industrial, Power by Liam Critchley

Conventional Li-ion batteries have been the staple battery technology in many devices, from phones to handheld monitoring equipment, for many years. Rather than looking into new batteries, companies are looking to further improve the status quo by incorporating nanomaterials into Li-ion electrodes.

Bidirectional Power over Ethernet

On December 27, 2019 in All, Energy Harvesting, IoT, Power by Charles Byers

Power over Ethernet combines data and power delivery over the same twisted pair cable. While standard PoE is unidirectional, driving energy from a PSE to a PD variants exist that are capable of transferring energy in either direction. This can have advantages in distributed IoT systems.

Accurate Fuel Gauging Through State-of-Charge Measurement

On December 4, 2019 in All, Power by Robert Huntley

Determining a battery’s state-of-charge using voltage alone is not an accurate method. By combining the open-circuit voltage, current flow, operating temperature, battery age, and discharge rate into a single algorithm, the Maxim MAX1730x series delivers a highly accurate fuel gauge for your product.

Solving BLDC Controller Design Challenges with the Qorvo PAC5556

On November 26, 2019 in All, Industrial, Motor Control, Power by Robert Huntley

Brushless DC motors have become a popular choice for use in a wide range of consumer and industrial appliances. Building a controller for a BLDC requires several key functions, all of which are combined in the single-package Qorvo PAC5556 Power Application Controller® (PAC™).

48V Electrical Systems Shift into High Gear

On November 18, 2019 in All, Automotive, Power by TDK

The development of so-called “micro hybrid” and “mild hybrid systems” based on 48V power has shifted into high gear. Learn how versatile automotive 48V electrical systems will reduce CO2 emissions and usher in practical, super-efficient electrical subsystems.

A Lesson from the Wind and the Sun

On October 31, 2019 in All, Power by Paul Golata

Gather round and let me tell you a story about the power of the wind and sun. These are gifts for us to enjoy. ADI is leading the way for humanity to harness their collective power through energy storage systems

Why SiC Devices Are Ideal for Level 3 EV Charging Applications

On September 24, 2019 in All, Power, Wide Bandgap by Robert Huntley

Charging an EV can be a lengthy process, however, Level 3 “fast” DC charging techniques promise much faster charging capabilities that reduce charging times to minutes instead of hours. This efficiency relies on high-speed power conversion, for which new wide-bandgap technologies are well suited.
