Test setup using DC metering approach for loss measurements of inductive components – principle, characterization, validation and application

IET Power Electronics, 2021
Accurate loss estimation of magnetic components is crucial for power electronics engineers. Unfortunately, loss predictions remain a quite challenging task, as these depend on many parameters and manufacturers typically do not deliver a sufficient ...

Tbit/s line-rate satellite feeder links enabled by coherent modulation and full-adaptive optics

Light: Science & Applications, 2023
Free-space optical (FSO) communication technologies constitute a solution to cope with the bandwidth demand of future satellite-ground networks. They may overcome the RF bottleneck and attain data rates in the order of Tbit/s with only a handful of ...

Non‐ideal behavior of ZVS inverter comprising variable and fixed frequency operation: Analysis, compensation, and verification

Power Electronic Devices and Components, 2022
This paper presents a study of a two-level inverter. It proposes a modulation scheme for inverters featuring zero-voltage switching (ZVS) with both fixed and variable switching frequency operation. The control scheme uses a hybrid method to determine the

Generalized Efficiency and the Uncertainty of Millimeter Wave Power Standard [PDF]

Advances in Radio Science, 2023
In the last decade, waveguide thermoelectric power sensors have been established as an alternative to thermistor mounts for millimeter wave power standards, and due to the detection principle and the nature of waveguides, the generalized efficiency is ...

Controlling Electromagnetic Fields

Science, 2006
Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...
