Electrical energy is supplied by the grid as AC, yet most devices that we use require DC power, meaning that AC/DC power supplies that make this conversion are one of the most common loads placed on ...

There have been spectacular improvements in efficiency in computing and consumer electronic products. A strong emphasis has been placed on the ac/dc “silver box” conversion. However, with the ...

While front-end ac-dc converters have changed significantly in terms of efficiency, density, and regulations, power factor issues continue to encumber the users of these supplies. It affects the ac ...

A Bridgeless PFC converter based on a novel switching method eliminates full-bridge rectifiers and helps to reduce the size and cost of switching power supplies. Last month, we described a ...

A new DC-DC power converter is superior to previous designs and paves the way for more efficient, reliable and sustainable energy storage and conversion solutions. The development can efficiently ...

When first starting an electronics project, it’s not uncommon to dive right in to getting the core parts of the project working. Breadboarding the project usually involves working with a benchtop ...

Green point-of-load DC-DC converter designs need high efficiency and low IQ, so what is the optimal POL converter for embedded systems. Most embedded systems are powered via a 48V backplane. This ...

Batteries aren't one-size-fits-all, and neither is the way they're wired to your house. Here's what you should know about AC- and DC-coupling. When we think about solar panels and batteries, we don't ...

The study’s first author LIU Shiqiang explains the device’s characteristics: “Its superior ‘voltage ratio’ means it can efficiently interface with a wide range of energy sources, while the ...
