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 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 ...

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 ...

Learn more about integrating GaN power FETs into switch-mode power supplies and what you must change when upgrading from silicon MOSFETs. The power-handling properties of GaN. The unique challenges of ...

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.

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.

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...
