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 ...

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 ...

Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

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 ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

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 ...

The proper installation of switch-mode power supplies in control systems is crucial to guarantee 24/7 availability and reduce problems associated with grounding faults, harmonic distortion, and other ...
