Conception of High-Frequency Power Planar Transformer Prototypes Based on FabLab Platform
Conceiving planar magnetic components for power electronic converters is very constraining, especially in the case of prototype development. Indeed, such making requires skills, specific appliances as well as human time for setting up the machine tools ...

Realization of a spherical boundary by a layer of wave-guiding medium
In this paper the concept of wave-guiding medium, previously introduced for planar structures, is defined for the spherically symmetric case. It is shown that a quarter-wavelength layer of such a medium serves as a transformer of boundary conditions ...

Characterization of low-noise quasi-optical SIS mixers for the submillimeter band [PDF]
We report on the development of low-noise quasi-optical SIS mixers for the frequency range 400-850 GHz. The mixers utilize twin-slot antennas, two-junction tuning circuits, and Nb-trilayer junctions. Fourier-transform spectrometry has been used to verify

A comprehensive design approach for a three‐winding planar transformer
In this paper, a new three‐winding planar transformer design with the integrated leakage inductor is proposed for a triple‐active‐bridge converter. It enables two output voltage levels: a high voltage (HV) output port and a low voltage (LV) output port ...
