Updated: 200A 1.2kV bidirectional switch module built around novel semiconductor

Ideal IPA01216DFx-HS block

Ideal Power is aiming to compete with smart IGBT modules, with a 1.2kV 160A (100°C, 240A at 25°C) power module built around its novel ‘B-Tran’ bi-direction semiconductor switch. Called IPA01216DFx-HS, it comes in an industry-standard 62mm package which includes an isolated driver circuit and “has significant advantages compared to IGBT modules, including lower losses and inherent bidirectionality”, according to the ...

Updated: Novel bipolar device drops only 0.6V in 1.2kV 100A circuit breaker

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 ...

Korea displays its ancient texts, with a little help from Tyne & Wear

Zytronic Korean interactive book

A priceless Korean medical encyclopaedia, first published in 1613, is now available for the public to interact with virtually the National Library of Korea Compiled by royal physician Heo Jun, the originals are locked away for safe keeping, but a high-resolution scan has been animated on a novel display surface by Seoul-based company Ubidus. “Many companies have developed digital books ...

Data hitches a ride on fast neutrons

Fast-Neutrons-300x200.jpg

Engineers at Lancaster University have transmitted, received and decoded data sent over a stream of fast neutrons. The proof-of-concept involved modulating neutrons from a calfornium 252 source using an Arduino-controlled mechanical shutter built from high-density polythene. Detection involved a one litre tank of scintillating meterial, a photo-multiplier and a ‘mixed-field analyser’ (made by Hybrid Instruments, based at the university) to separate ...

More on: Thin-film source-gated transistor promises denser circuits

UofSurrey-source-gated-transistor-analogue-blocks

Announced yesterday, researchers from Surrey and Cambridge universities and the National Research Institute in Rome have used thin-film source-gated transistor (SGT) to create compact analogue circuit building blocks that can be used on flexible substrates. Source-gated transistors – SGTs – are uni-polar – they only need n or p-type semiconductor, not both. The research team built two two-transistor building blocks: ...

Cuttable phone charger – who would have thought?

Tokyo-Uof-Takahashi-cuttable-wireless-charger

A Japanese research engineer has created a thin flexible wireless charging array that can be cut to size with scissors in almost arbitrary ways. “You can do more than just cut this sheet into fun or interesting shapes,” said Ryo Takahashi of the University of Tokyo. “The sheet is thin and flexible so you can mold it around curved surfaces ...
