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 ...

The best news when you power up a prototype supply board for the very first time is when it not only works, but also runs quiet and cool. Unfortunately, this does not always happen. A common problem ...

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 ...

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 ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

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.

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 ...

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 ...

Toshiba Electronics Europe GmbH has added the DTMOSVI 600V HSD (High-Speed Diode) N-channel power MOSFETs to the DTMOSVI 600V Series, featuring a super junction structure. The seven new products are ...

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 ...
