Vacuumschmelze (VAC) is exhibiting first cores and common
mode chokes made of the nanocrystalline material Vitroperm 550
HF at PCIM. The newly developed alloy enables next-generation
components with optimized size and weight.
The constant demand for smaller and lighter systems is also a
challenge in power electronics. With the material innovation Vitroperm 550 HF low-cost cores, chokes or power transformers in
compact design for demanding requirements can be realized. The
components showa significantly improved high-frequency behaviour compared to solutions made of Vitroperm 500 F or typical
EMC ferrites.

Network planning and low/high-frequency software speeds development of smart connected systems and electric motors

Applications for the high-performance materials such as switched
mode power supplies, wind or solar inverters and frequency converters. In the automotive sector, common mode chokes in the
drive train offer enormous advantages in size - components that
are up to 60% smaller can be produced cost-effectively.

Altair (Nasdaq:ALTR) has released the 2018 versions of leading
electromagnetic (EM) simulation software FEKO, WinProp, Flux
and FluxMotor. These electromagnetic solver tools, part of Altair's
HyperWorks, The Platform for Innovation, are widely used to accelerate the global design process for the automotive, aerospace,
defense, communications, consumer electronics, energy, and
healthcare industries.
"We are excited by the latest release of our electromagnetic tools
to support our customers as they move toward broad deployment
of products relevant to e-mobility and communications, Industry
4.0 and the Internet of Things. The range of applications covers
electromagnetic problems across the whole frequency range from
DC into THz, integrated within Altair's multiphysics modeling environment for multidisciplinary system optimization," said Ulrich
Jakobus, senior VP for EM Solutions at Altair.
The rich set of features in the 2018 release of the HyperWorks
electromagnetic simulation solutions portfolio broadens functionality, simplifies workflows, and enhances the user experience. For
example, a novel workflow has been implemented in FEKO 2018,
that facilitates characterizing multi-layered dielectrics. With this,
transmission loss and bore-sight error can be computed for arbitrarily shaped radomes more efficiently and with greater flexibility
than ever before. Another example is the addition of new features
in Flux 2018 bringing new capabilities for CAD geometry simplification and meshing, improving workflow, and increasing flexibility
with the ability to solve faster in 3D using new HPC resources.

Furthermore, power transformers with significantly reduced core
losses can be realized for the use in wall boxes or in on-board
charging systems for charging electric vehicles.

Long-term Flux customer Valeo, is a leading automotive supplier
working on e-mobility. "After a short online presentation, I was
able to connect my Flux project to HyperStudy optimization software and obtain my first results in 30 minutes. I was very pleasantly surprised," notes Jean-Claude Mipo, advanced technology
manager at Valeo.
