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 ...

Layout of a switch mode power supply has a major effect on its performance. Along with magnetic design it is one of the high impact points in the design process. In this part I will review the ...

An effective and long-lasting power supply is the backbone of any IoT device. Switch-mode power supplies (SMPSs) are undoubtedly good for powering IoT devices, but most of them are bulky and expensive ...

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.

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

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 ...

[David], [Ian], and [Sajjad] finished and submitted their entry to the ChipKIT challenge just under the wire. They designed and built a maximum power tracking circuit for use with renewable sources.

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original parts. But when said power ...
