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 ...

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 ...

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 ...

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

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.

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 ...

STMicroelectronics’ SRK1004 synchronous-rectifier controllers save space and increase efficiency in the secondary side of active-clamp ...
