Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Sponsored by Texas Instruments: What are the best methods for maintaining the high efficiency of a SMPS without suffering from the detrimental effects of EMI? Switch-mode power supplies (SMPS) are the ...

Bill Traue, CSRE, 8-VSB, AMD is principal of Bill Traue Technical Services. He acknowledges that when it comes to fixing dead switched-mode power supplies, the small wall-wart or line-lump type aren’t ...

High-speed converters and power modules pose tough challenges to designers. Switching losses shall be reduced as much as possible, meanwhile, high dI/dt and fast dV/dt switching shall be properly ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

I am pondering sfx power supplies. End goal, have it run in zero rpm mode as much as possible if not always that way. I do not see any fanless sfx power supplies, only atx. As such, what is the driver ...
