Aside from apparently having both the ability to reproduce on their own and simultaneously never being around when you need one, USB chargers seem innocuous enough. The specs are simple: convert mains ...

SMPS is the abbreviation of switching mode power supply, a kind of high-frequency power conversion device and a power supply device. Its function is to convert a level of voltage to the voltage or ...

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 ...

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 ...

An industry expert addresses the debate of discrete components vs. external boxed filters for suppressing noise. The analysis and suppression of electro-magnetic interference (EMI) generated from high ...

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 ...

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.

Toshiba Launches 100V N-Channel Power MOSFET with Its Latest Generation Process Technology[1] to Improve Efficiency in Switched-Mode Power Supplies for Industrial Equipment Toshiba Electronic Devices ...

Leveraging ST’s robust silicon-on-insulator (SOI) process, the SRK1004 can control the MOSFET in either low-side or high-side ...

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 ...

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 ...

[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 ...
