Got Current Spikes? Soft-Saturation Inductors to the Rescue!
Featured Article - Submitted by Mike Donnelly on Tue, 12/15/2015 - 08:52Design requirements often focus on steady-state performance and operating conditions. Component sizing and ratings selection, if based solely on meeting these objectives, can lead to unexpected and sometimes catastrophic results. Parts may be most severely stressed during transients that occur infrequently, perhaps only once during the initial start-up!
Automotive Start-Stop … Keep the lights ON!
Featured Article - Submitted by Mike Donnelly on Mon, 06/13/2016 - 15:10You’ve probably noticed when you start your car that some of the optional electronics turn off, such as the radio and some LED lighting circuits. That’s because the high current draw of the starter motor pulls the system voltage far below the normal 12+ volt operating level. Critical circuits are designed to operate at these low voltages … if the ignition circuit didn’t work, you would be cranking for a very long time! But many functions are not designed for that low-voltage condition.
