Programmable AC Source line now includes compact single- and three-phase models
Chroma Systems Solutions, Inc., a provider of power conversion test equipment, announces the addition of three new models to their growing programmable AC power source product line. The 6150/7/8/9 are programmable and now include 3 kVA, 4.5 kVA, and 6 kVA versions in either single- or three-phase outputs without derating under SCIP program control. Frequency range […]
Powering battery-free low-power sensors, embedded circuits, wireless devices
Smart suitcases can be wirelessly tracked, they can weigh themselves, and their locks can be opened and closed by remote control. But all such luggage now depends on batteries, which run down and can also, in some cases, explode. The Face Companies of Norfolk, Virginia, announced today that they’ve solved the problem that’s been inhibiting […]
Dual-input boost-buck charging ICs support USB Power Delivery spec
A growing number of portable devices, including notebook PCs, are adopting the USB Type-C PD standard that can charge up to 100W, providing a common charging platform. At the same time wireless charging is gaining traction, increasing the demand to support both charging methods. However, in order to deliver a wide power supply range required […]
