      Power supply sequencing in spaceflight systems (02/07/2018)

      Intensive processing digital loads require multiple rails to power their circuitry, and the necessary devices demand very specific rail power-up and power-down sequencing to guarantee operational efficiency. Add the complexity of spaceflight operation and system designers have limited ways to implement the power sequencing requirements.

      Innovative power solutions for transportation systems (03/05/2018)

      Transportation systems can have input voltage ranges up to 14V (single battery automotive), 28V (dual battery trucks, buses, trains, airplanes), or even higher, as well as requiring one or more low voltage rails for digital systems. As a result, designers of such systems need to know how they can step down from high input voltages simply, efficiently and reliably.

      Why thermal management is crucial to the design of electric vehicles (06/04/2018)

      Following the UK government’s (and many other countries') announcement to ban the sale of new petrol and diesel cars from 2040, there is likely to be a seismic shift in the automotive industry, as lithium-ion battery-powered cars are likely to become the de facto standard for road cars. Accordingly, 6SigmaET look at the importance of thermal management in EVs...

      Improving farming efficiency with a 21st century gate (12/03/2018)

      Dofygate is a fast-opening, electric gate that requires no external power, available in 2-, 4- or 7-bar versions, with spans of 2 to 6 metres. Solar-powered, it can be operated from a vehicle using a fob, or via a phone app or keypad, and is self-closing. Made from carbon fibre, the gate is strong enough to resist accidental contact from livestock.
