The term DC link has traditionally referred to the junction between two power conversion stages where an energy storage element (almost always a capacitor) acts as a buffer for each. A classic example is the capacitor placed between the rectifier and the voltage source inverter in a mains-supplied variable frequency drive (see Fig. 1). This… Read more »

The monster that wouldn’t die—varied reactions to GM’s electric Hummer unveil
EV fans tend to be divided into two groups: Greenies and Car Guys, and reaction to GM’s upcoming Hummer EV has, unsurprisingly, been divided along those lines. Hummer good Most of the media is ecstatic over the new machine. Many are praising its “bad-ass” looks (GM says it wanted to make it look “less military”… Read more »
3 factors that impact gap filler reworkability in EV battery packs
Sponsored by Parker LORD The design of electric vehicle battery packs may vary among manufacturers but commonly, the battery is attached to its cooling plate not only with fasteners but also thermally conductive polymeric materials called gap fillers. Gap fillers can outperform thermal pads in this application to achieve lower thermal impedance, as the gap… Read more »
