MOSFETs have been the chosen transistor technology in most Switched Mode Power Supplies (SMPS) since the mid 1980’s. MOSFETs are used as the main switching transistor as well as to improve efficiency ...

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 ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

Allegro MicroSystems, LLC announces the release of three new switch mode power supplies. Three switch mode power supplies from Allegro MicroSystems, LLC, the C, HWB and SWF series, have been designed ...

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 global market for battery-powered applications is rapidly growing, including power tools, service robots, light electric vehicles, and many others. The evolution of switched-mode power supply ...

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 ...

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 ...

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.

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 ...
