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 ...

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 ...

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight, ...

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 ...

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.

Question: Where Should the Coil Go? Answer: Switching regulators for voltage conversion use inductors for temporarily storing energy. These inductors are often very large components and must be ...

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 ...

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 ...

The Rhino line now includes ac/dc switch-mode power supplies encapsulated in an ultracompact, low profile housing. The new PSE Series is for space-limited applications and screw mounts to a panel or ...

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 ...
