Regenerative braking: A closer look at the methods and limits of regen

All motors are generators, the old saying goes, with the caveat that few types are equally good at both modes of operation, and some are downright awful as generators (a classic example being the single-phase shaded pole induction type, used in myriad small appliances the world over). Fortunately, both types of AC motor commonly used… Read more »

A closer look at film capacitors

Plastic film capacitors relentlessly continue to take over many of the duties in EV power electronics that were once performed by the venerable aluminum electrolytic type, mainly because film capacitors exhibit much lower losses and have a much longer operational lifespan, especially at ambient temperatures in the 75-85° C range. The tradeoff is that film… Read more »

TDK creates durable DC link capacitors, extends capacitance and voltage ranges

TDK has improved its DC link EPSCOS film capacitors, which can now handle a variety of worst-case-scenario environmental conditions. Besides being a mouthful, the B3277*H series can operate at temperatures as high as 105° C with voltage ranges of 450 VDC-1,100 VDC and capacitance values of 1.5 µF-120 µF. These capacitors are designed for use with DC… Read more »
