How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...

The influences and tolerance that impact SMPS voltage accuracy. Tools that can be used to optimize a power-converter circuit loop and measure load transients. Switch-mode power supplies (SMPS) have a ...

Power supply design has traditionally placed a high priority on energy efficiency. The system and the end user will pay more if the power supply is inefficient and has non-negligible power losses. Let ...

I have a couple of Chinese programmable lab power supplies. Both switch mode power supply (SMPS) systems are rated for 110V-220V AC input. But the UNI-T UTP1306 power supply has an input voltage ...

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 ...

After we last saw [David Lovett] of [Usagi Electric], he was knee-deep in trying to fix a DEC PDP-11/03 power supply, which fortunately led to a fixed PSU and a very happy PDP-11/23 system installed ...
