Galvanic isolation between the high-voltage and low-voltage sides.

Wolfgang Rambow, Senior Director Reference Design EPCOS, a TDK Group Company

TDK has joined forces with Infineon Technologies to develop a design for xEV inverters that achieves a very high efficiency of over 98 percent over a power range of 10 kW to 150 kW. This success has been achieved by matching of the Infineon IGBT module and the EPCOS and TDK passive components. The new Infin

Interference-free cabling

Interference-free cabling

Martin Tenhumberg and Werner Wölfle, Traco Power

Long lines for distributed loads can emit and be susceptible to interference which can affect the connected loads. However, the loads work without disruption as long as a few basic rules are observed when it comes to cabling. Moderndevices and systems are generally complex, their electrical/electronic components

Wuerth Elektronik and FELA collaborating on research into new technology

Despite current stability and positive sales growth in the circuit board indus-try, it must be presumed that consolidation has not yet come to an end. Circuit board manufacturers are facing enormous price erosion caused by Asian circuit boards, as well as rising manufacturing costs in Europe and generally intense g

UV radiation from a relativistic electron beam is diffracted by a double-slit. In contrast to the normal light (left), the diffraction shows a deformation in the central part (right), indicating the existence of the phase singularity, which is a definite evidence of the vortex nature.

Vortex Photons From Electrons in Circular Motion

National Institutes of Natural Sciences

Researchers at IMS and their coworkers have shown theoretically and experimentally that a high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays. This greatly broadens application spectra of the vortex photons in the field of phy
