Abstract: This paper presents an electrolytic-capacitor-less LED driver. The driver is made up by the integration of two converters in parallel. The first converter is a Buck-boost used to deliver ...

Abstract: This article proposes a brushless multiexcitation generator (MEG) using parallel magnetic circuits for dc power system with enhanced output power capability. The multiexcitation sources ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.
