The never-ending drive towards smaller and lighter products poses severe challenges for the power supply designer. In particular, disposing of excess hear generated by power semiconductors is becoming ...

Simply put, designing a power supply is a major undertaking. After making your build vs. buy decision, you face a myriad of circuit choices—more than you probably realize. Building a power supply used ...

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 ...

In the second part of this two-part article, the authors describe how to determine the efficiency losses associated with passive components and how features offered by controller ICs can be used to ...

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 ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

[Erich] spotted a broken DVD recorder at a local amateur radio meeting and decided to see if he could restore it to working order. While he was fortunate enough that someone labeled it as having a bad ...

Buffalo Grove, IL - Carlo Gavazzi is proud to introduce its expanded line of three-phase power supplies. The SPD Series 3-Phase Switch-Mode Power Supplies are offered in 120, 240, 480 and 960 watt ...

Dublin, Aug. 26, 2020 (GLOBE NEWSWIRE) -- The "Global Switch Mode Power Supply Transformers Market By Type (AC to DC, DC to DC, DC to AC and AC to DC), By End User (Consumer Electronics, ...

The Rhino line of power supplies has been has been expanded to include the PSE series of AC/DC switch-mode power supplies encapsulated in an ultra-compact, low profile housing. The series features a ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

On paper, electricity behaves in easy-to-understand, predictable ways. That’s mostly because the wires on the page have zero resistance and the switching times are actually zero, whereas in real life ...
