Top circuit protection considerations for DC fast chargers, a new class of high-voltage consumer electronics

DC fast charging isn’t just a godsend for EV drivers looking for a quick charge. It’s also an entirely new level of consumer electronics. “You and I, as members of the general public, have previously never had access to anything higher in voltage than what we see at home in our wall socket,” Tim Patel, Global… Read more »

Top causes of failure in power semiconductors

All electronic devices eventually die, and the failure can be quite spectacular if suitable foresight and care was not employed during the design and construction phases, especially if the device handles high power or is supplied by a large battery. It should go without saying that both conditions apply to much of the electronics inside… Read more »

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 »
