Supercapacitor battery charges in seconds and lasts a week
Breakthroughs in battery technology are becoming increasingly common these days, a manifestation of years of multi-billion dollar R&D investments focused on advanced materials science in hot pursuit of a compact, renewable energy sources by the world’s automobile and electronics makers.
Power supplies win safety standard approval
The CoolX600 Series of 600W convection-cooled modular power supplies from Excelsys Technologies is now approved to IEC 62368-1 – Part 1, the new safety standard for audio, video, information and communication technology equipment. The standard has been created to provide a single approval covering the increasing overlap in design and functionality of professional and domestic equipment.
Hybrid capacitors combine technologies to get the best of both worlds
Supercapacitors are commonly used wherever a quick energy boost is needed, as an alternative to a rechargeable battery. The most prevalent type of supercapacitors, EDLCs (Electrical Double Layer Capacitors), provide thousands or tens of thousands of times the capacitance of normal capacitors while their energy density makes them ten times smaller than batteries (more here about how EDLCs work in detail).
VCA meets ultra-small requirements for precise control
Medical devices are often smaller and lighter in weight than the vast majority of applications that require some type of motion control, simply because they are often portable/mobile, hand-carried or lifted. Internal components needed for these devices are chosen carefully in order to make for the smallest overall device footprint. This poses unique challenges to component manufacturers supplying the medical market.
Power switch supports USB Type-C delivery and fast-role swap
The DPS1133 single-channel power switch introduced by Diodes Incorporated is a high-voltage power switch designed to meet all the demanding protection and fast-role swap requirements of USB Type-C ports. As such, it addresses the full gamut of mobile and desktop computing devices and peripherals, and other applications in the consumer electronics, mobile communications, industrial, and medical markets, such as smartphones, AR/VR goggles, rob...
Generator connection point mitigates power failure
A new generator connection point (GCP) has been launched by power distribution specialist ide Systems, to mitigate down-time caused by mains power failures. The product, suitable for office buildings, healthcare facilities and retail blocks, allows backup generators to be quickly and easily connected in the event of an unforeseen electrical failure.
Power measurement software provides PC connectivity
WTViewerE software provides PC connectivity for Yokogawa’s power analysers - including the WT3000E, WT1800E, WT500 and WT300E models - via Ethernet, USB, GPIB or RS232 interfaces. This connectivity allows users to easily control, monitor, collect and analyse measurement data, and save measurements remotely.
Why DC only distribution makes sense for energy savings
The drive for energy conservation, the DC basis of modern electronic systems, and the development of renewable energy sources have converged to challenge the 100 year old assumption that AC alone is the single best means of distributing electricity.
Understanding ESR in electrolytic capacitors
Today’s microprocessor-based systems require power sources that deliver high current and ultra fast transient performance, with tight regulation. This creates a need for cost effective, compact capacitors with high capacitance values. Electrolytic capacitors are the solution of choice but it’s important to go beyond specifying capacitance and voltage to consider Equivalent Series Resistance (ESR) as a figure of merit.
Next-gen programmable DC power supplies deliver 5kW output
TDK has announced the introduction of the TDK-Lambda Genesys+ series of high power density programmable DC power supplies - the 5kW, 1U model is the first in the series. Utilising DSP (Digital Signal Processing) technology, these next-generation units provide improved efficiency, performance and functionality over existing products available on the market at a competitive cost.
