A New Power-Cycling Strategy for Testing the Reliability of Power Electronics Modules

Dr. John Parry, Mentor Graphics Corp.

The particular power cycling strategy you choose for high-power semiconductor devices, such as power transistors, diodes, MOSFETs, and IGBTs, during reliability tests can have a significant effect on predicted lifetime results even if the tests have similar initial parameters. Also, how you set up the measurements can affect the results of the power cycling tests. Read more about A New Power-Cycling Strategy for Testing the Reliability of Power Electronics Modules

Battery Diagnostics On-the-Fly: Removing the “Black-Box” Stigma by Making Performance Transparent

Isidor Buchmann, CEO & Founder, Cadex Electronics, Inc.     

Battery users imagine a battery pack being an energy storage device that resembles a fuel tank dispensing liquid fuel. For simplicity reasons, a battery can indeed be perceived as a vessel storing electrical energy; however, measuring energy flowing into an electrochemical device and then drawing it out again is far more complex than handling liquid fuel. While a hydraulic fuel gauge measures liquids moving in and out of a tank of known size, a battery fuel gauge reads units of current. Battery size is specified in ampere hours (Ah), and what makes estimating battery state-of-charge (SoC) and state-of-health (SoH) so challenging is an unsteady state; a battery loses capacity with each charge and leaks energy in the form of self-discharge.

Improve Tab to Terminal Connections in Battery Pack Manufacturing

Geoff Shannon, Amada Miyachi America, Inc.

Battery packs have become an integral part of everyday life, powering a growing range of portable electronic devices, cordless power tools, energy storage, and hybrid and electric vehicles. Tab to terminal connection welding is one of the key battery pack manufacturing applications. Manufacturers need equipment, systems, and automated lines that meet quality and production requirements for these products. Both resistance and laser products are well suited to integration into production lines that may be either standalone or automated operation. To maintain the required throughput that offers high quality and yields, users must have a clear understanding of which process is best for the particular battery pack size, tab and terminal material, type, and thickness. In addition, the selected process and integration solution should include process monitoring, process data management, and weld quality assessment.
