Pre-Switch kondigt cross-Platform Soft-Switching technologie aan die gebruik maakt van kunstmatige intelligentie.
CAMPBELL, Californië.–(BUSINESS WIRE)– Pre-Switch, Inc., ‘s werelds grootste leverancier van soft switching technologie, presenteert vandaag de Pre-Flex™ technologie, een geïntegreerde AI (Artificial Intelligence) controller IC (Integrated Circuit) die effectief alle transistor schakelverliezen in hard geschakelde architecturen voor vrijwel elke power converter topologie elimineert.
Pre-Flex verlaagt kosten, grootte en gewicht drastisch, terwijl het de efficiëntie en betrouwbaarheid van stroomomvormers in de server-, zonne-, wind-, EV-, tractie- en motoraandrijfmarkten verhoogt.
Pre-Flex technologie leert en past “in het systeem” aan, cyclus per cyclus, om resonante soft-switch betrouwbaar te forceren over veranderende belastingen, ingangsspanningen, temperaturen en productietoleranties. De technologie heeft bewezen dat de efficiëntie groter is dan die van topologieën op vijf niveaus tegen een fractie van de kosten en complexiteit.
Pre-Switch Announces Cross-Platform Soft-Switching Technology Using Artificial Intelligence
CAMPBELL, Calif.–(BUSINESS WIRE)– 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.
