Omron is aiming to replace conventional contactors with its most powerful ac PCB relay yet: G9KA-1A-E, which handles up to 1kVac and carries up to 300A. Sitting on a 51 x 51mm footprint, the relay is 54.5mm tall and weighs ~235g. The contacts are cadmium-free silver alloy and offer 200μΩ on-resistance (at 200A). Maximum timing is 30ms make and 10ms ...
Ideal Power has launched the first commercial version of its novel bi-directional semiconductor power switch, a multi-die module rated at 1,200V 100A (25°C, 50A 100°C) aimed at solid-state circuit breakers (SSCBs) and matrix converters. Updated below to include driving requirements Called IPAM01210C10, “the power module was designed specifically to enable SSCBs to deliver very low conduction losses, while operating orders ...
Jetperch has releases a second generation of its Joulescope precision power consumption measurement instrument. Called JS220, it has a huge dynamic range: ±3A max (10A peak) with 500pA resolution over six 16bit auto-ranges – equivalent to 34bit – which allows the measurement of both active and sleep power. It has a bandwidth of 300kHz backed by a 2Msample/s conversion – simultaneously ...
Toshiba has created a gull-wing mosfet package specifically for high current automotive applications, and has released a 400A 40V mosfet in it. Branded L-TOGL and measuring 9.9 x 11.8 x 2.3mm (right), the AEC-Q101-capable package is designed for up to 175°C, 100V, 400A, 750W, with minimum mosfet device Rds(on) around 300μΩ. This compares with 250A, 372W and ~740μΩ from the ...
Winner CCell – Digital living reefs Digital living reefs grow natural rock using seawater electrolysis and mimic the behaviour of natural coral reefs. CCell reefs protect coastlines by interrupting waves before they reach a shore, while providing an ideal habitat for marine life, providing long-term living ecosystems. One judge said: “I was impressed by the truly innovative product and ...
Infineon has used silicon-on-insulator technology to create a 140V three-phase gate driver for motor drives. Called 6ED2742S01Q, it is designed to drive six external n-channel mosfets using bootstrapping for the upper three, but it unusually includes low-power charge pumps to allow 100% duty cycle high-side operation. For traditional bootstrapped operation, three diodes are monolithically integrated to avoid the need for ...
The UK’s Satellite Applications Catapult is funding research into a future Space-Based Solar Power (SBSP) system. The aim is help create a fully renewable baseload energy technology. The total project value will be £620k, which is funded by a £465k grant from the UK Space Agency and a further contribution from the Satellite Applications Catapult itself of £155k. It will ...
Sub-millimeter microtubular (hollow fibre) bundled membranes could shrink the size of flow battery reactors, according to the Georgia Institute of Technology. In a proof-of-concept zinc-iodide battery, the reactor part achieved 306.1W/litre discharge and charging at 1,322W/litre. Key to the concept is using tubes-within-tubes to make the reaction vessel into a self-supporting structure – doing away with the volume-consuming support hardware ...
A UK energy company has accelerated growth plans to expand its domestic power products, build a new HQ in Lincolnshire and open offices around the world all in the space of six years, writes Steve Bush. Myenergi is an electric car charger and renewable energy controller company based near Grimsby in Lincolnshire, where it designs and manufactures its own products. ...
The demand for autonomous devices in IoT and related applications has been increasing. However, for engineers and designers developing maintenance-free power sources, there remain challenges of the long list of requirements in storage, discharge, and installation. More specifically, these challenges include achieving low internal resistance, small self-discharge, constant voltage charge, remaining durable in a fully charged state, long cycle life, ...
