Power Utility Replaces Aging Transformers with Customized, Drop-in Units

Ed Sullivan, Writer

As power transformers at generation facilities near end-of-life cycles, a number of potentially dangerous events can come into play – in addition to untimely power outages and costly repairs. Because many transformers are exposed to dust and high operating temperatures, over time they incur such problems

Noise Sensitive Applications Want Ultralow Noise LDO Regulators

Amit P. Patel, Senior Design Engineer, Power Products & Steve Knoth, Senior Product Marketing Engineer – Power Products, Linear Technology Corporation

Linear Regulators are integrated circuits that step a voltage down from a higher voltage to a lower voltage without the need of an inductor. The low dropout linear regulator (LDO) is a special type of linear regulator in which the dropout voltage – the differential between the input-to-output voltages needed to

Determining the State of Health of Batteries Quickly and Precisely

Dipl.-Ing. Andreas Mangler, Rutronik, Dr.-Ing. Olfa Kanoun and Dipl.-Ing. Thomas Günther, Chemnitz University of Technology

When Li-ion batteries age, their performance drops. Current methods still require complex instrumented laboratory-based tests to determine how quickly and to which degree this occurs. In contrast, a procedure developed by Chemnitz University of Technology now enables quick and precise diagnosis. It ensures the re

Figure 1. Power rail voltages and tolerances required by ICs continue to decrease. These dynamics challenge traditional oscilloscope measurement approaches as the noise of the scope and probe system impairs the ability to make accurate measurements of small signals.

Precise Power Integrity Measurements

Joel Woodward, Strategic Oscilloscope Planner at Rohde & Schwarz in Munich

Development teams face increasing power integrity challenges. FPGAs, ASICs, and standard components semiconductor devices continue to increase in gate count. Each of the millions of gates on an integrated circuit requires current to switch. As devices can consume tens of amps and total power must be managed, DC

Probing Tips for High-Performance, Low-Power Circuits

Andy Heltborg, Tektronix

Low-power circuits combine high speed and low-power consumption in a single component, presenting a number of probing and testing challenges. Since many low-power devices are also high-speed systems, there is a need to test and verify their performance. Testing the low-power components for compliance with industry st
