The demand for greater energy savings is constantly increasing. For product designers, this means paying attention to the key parameters of power devices, including high efficiency and low standby ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...

Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power ...

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 ...

Viper31 is a mains voltage converter for ac-dc power supplies from STMicroelectronics which allows PSUs to be constructed that consume only 20mW no-load at 230Vac, while delivering up to 18W when ...

Recom has created a wide input range 1.5 x 2inch 15W ac-dc converter that operates over part that operates over 18 – 264Vac, or 18 – 375Vdc. All parts have a 40 x 52.5mm footprint and stand 25.5mm ...

Novel MinE-CAP device dramatically reduces the input bulk capacitor size, reduces in-rush current by up to 95%, eliminates NTC thermistors and associated losses SAN JOSE, Calif.--(BUSINESS ...
