Protect your site from the effects of poor power quality
Powerstar has launched a Power Quality Service that enables companies to protect their site from the effects of poor power quality issues. The service will deliver a power quality audit to identify problems, suggest solutions and commission the installation of effective equipment to rectify any issues identified.
Solid-state electrolyte could lead to the "perfect" battery
If you pry open one of today’s ubiquitous high-tech devices - whether a cellphone, a laptop, or an electric car - you’ll find that batteries take up most of the space inside. Indeed, the recent evolution of batteries has made it possible to pack ample power in small places. But people still always want their devices to last even longer, or go further on a charge, so researchers work night and day to boost the power a given size b...
50W power supplies target heavy-duty industrial applications
The MIW-50-D0-IP66 series of compact, 50W power supplies are designed for applications that require a low power, rugged waterproof, dust-proof, explosion-proof AC/DC or DC/DC power solution. The units operate across a full universal input range of 90V to 264VAC and provide a single output of 5, 12, 24, 36, 48, 72, 130VDC or custom. The series also offers dc-inputs of 250VDC (210-290V), 300VDC (250-350V) or custom.
Multiphase sync-buck DC/DC controller uses 6-bit VID
Linear's LTC3877 is a dual output multiphase synchronous step-down DC/DC controller with 6-bit Voltage IDentification (VID) control that enables 10mV output voltage step resolution, a necessary feature when powering FPGAs and ASICs with tight input voltage requirements. The LTC3877 operates from input voltages of 4.5 to 38V and produces a fixed output voltage from 0.6 to 1.23V when using VID and up to 5V without VID.
Charge your phone with two AA batteries
Not being able to charge our phones at any given time is a struggle, but this is changing. The Nipper is a small portable phone charger. It's so small users can carry it wherever they go and it can easily attach to keys. It doesn't need to be charged and only relies on AA batteries, which can be found anywhere around the average household or bought in any shop on the go.
Preventing fires in next-gen lithium batteries
In a study that could improve the safety of next-gen batteries, researchers at Stanford University discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites, ‘fingers’ of lithium that pierce the barrier between the battery’s halves, causing it to short out, overheat and sometimes burst into flame.
Sync buck DC/DC controller enables use of DrMOS
Linear Technology Corporation has announced the LTC3887-1, a dual output synchronous step-down DC/DC controller with I²C-based PMBus interface for digital power system management. The LTC3887-1 differs from the previously released LTC3887 by providing a three-state PWM signal, enabling the use of DrMOS, power blocks or similar power stages.
Wireless power receiver IC matches wired charging speeds
Toshiba has launched a wireless power receiver IC that will enable mobile devices to be charged wirelessly, as fast as if they were connected to the charger via a cable. The TC7764WBG supports a maximum power output of 5W and is compliant with the Qi standard’s low power specification V.1.1.2, defined by the Wireless Power Consortium (WPC).
Li-ion batteries can be printed on almost any surface
On July 15, a team of researchers at UNIST, led by Prof. Sang-Young Lee have discovered a class of printable solid-state Li-ion batteries (as referred as PRISS Batteries) that can exist on almost any surface. According to the research team, conventional rechargeable batteries come in fixed shapes and sizes, which have intrinsic limitations in fulfilling design and performance requirements for the flexible and wearable electronic devices.
5-20W open power supplies are medically approved
Designed to provide up to 20W for medical equipment applications, Powersolve announces the PMP05, PMP10, PMP15 and PMP20 series of single output power supplies. Each series is comprised of four models featuring Class II isolation, an open frame format and, importantly for medical applications, cooling by free air convection. Every model has been burn-in tested at full load.
