Pre-Switch Announces Cross-Platform Soft-Switching Technology Using Artificial Intelligence

Jaa

Pre-Switch, Inc., the world’s premier supplier of soft switching technology, today introduced Pre-Flex™ Technology, an embedded AI (Artificial Intelligence) controller IC (Integrated Circuit) which effectively eliminates transistor switching losses in hard-switched architectures for virtually any power converter topology. Pre-Flex dramatically reduces cost, size and weight, while increasing efficiency and reliability of power converters in the server, solar, wind, EV, traction and motor drive markets.

Pre-Flex technology learns and adapts “in-system,” on a cycle-by-cycle basis, to reliably force resonant soft-switch across changing loads, input voltages, temperatures and manufacturing tolerances. The technology has proven efficiencies greater than those of five-level topologies at a fraction of the cost and complexity. Pre-Flex also significantly lowers EMI (Electromagnetic interference) and dramatically decreases dV/dt for any switch type. Pre-Flex enables Silicon carbide-like performance for low-cost IGBTs, and allows SiC- and GaN-based topologies to switch up to 20x faster than they do today. Built into the architecture are innovative cycle-by-cycle safety features and communications that were never possible before. Pre-Flex has switched 900V Wolfspeed SiC MOSFETs up to 1MHz, and 650V Infineon IGBTs at over 100 kHz with unprecedented efficiencies. The technology presently scales from 1 KW to above gigawatts.

“We have removed the biggest barrier to advancing the power conversion industry,” said Bruce Renouard, chief executive officer of Pre-Switch, Inc. “Our technology enables simple, reliable and cost-effective forced resonant soft-switching on any topology.”

Pre-Switch is working with development partners interested in leading their respective industries by designing their next-generation power converters with Pre-Flex technology.

“By significantly reducing IGBT switching losses without increasing dV/dt, Pre-Switch is creating a possibility to redefine our VFD motor drives to be smaller and more efficient without being harmful to motor insulation and bearings,” said Adalberto Jose Rossa, Drives R&D manager of WEG Drives & Controls. “We are investigating this technology, and initial test results at double-pulse and at short-circuit conditions have inspired us to test a complete drive with Pre-Switch technology. We look forward to analyzing reliability data of the system under real motor load conditions.”

“The higher switching frequencies enabled by Pre-Switch are able to provide a lower motor current ripple,” said Carlos Afonso Hümmelgen, Drives R&D coordinator from WEG Drives & Controls. “Lower motor current ripple yields reduced motor harmonic losses, and increased motor and system efficiency.”

Pre-Switch will be at PCIM Europe 2018 in Nuremberg, Germany, at booth 6-147 in Hall 6.

Boehringer Ingelheim bolsters biologics research and development with 230 million euro investment in new development center22.6.2018 15:00Tiedote

Today Boehringer Ingelheim announced a 230 million euro investment into a new Biologicals Development Center (BDC) at the company’s Research and Development site in Biberach, Germany during the foundation stone laying for the new center. “The BDC is another key building block supporting the company’s long-term strategy for increasing the pipeline’s share of biologicals. This is particularly driven by two of our core areas, immune oncology and immunology,” says Dr. Fridtjof Traulsen, Corporate Senior Vice President Development at Boehringer Ingelheim. “The share of new biological entities in Boehringer Ingelheim’s research pipeline has been consistently increasing over the past few years and has now reached forty percent.” The BDC will help to maximize synergies by integrating biologicals analytical and process development as well as manufacturing for clinical studies into one seamless unit, while at the same time increasing development capacity.

Announcement by Viking Corp on Tecnotree22.6.2018 14:09Tiedote

In the interests of stakeholder transparency, this announcement provides background and context to Viking's file bankruptcy proceedings upon Tecnotree: As many of you will now know, Viking Corp was recently forced to file bankruptcy proceedings upon Tecnotree, which were withdrawn on the 19 June. In the interests of stakeholder transparency, we make this Announcement to provide background and context to this action. Firstly, we would reflect on the recent history of our attempts to partner with Tecnotree and all its stakeholders. Viking launched a Tender Offer (TO), having conducted detailed discussions with the Tecnotree Board and our advisors. On the basis of those discussions, we were very confident that the TO price of 10 cents per share provided truly superior value for shareholders. So did the Tecnotree Board as evidenced by their unanimous recommendation of our Offer and of course, further evidenced by the current prevailing market price. This TO was supported in the most vigoro
