Analysis of buck-boost converter inductor loss using a simpleonline B-H curve tracer [PDF]

, 2000
A simple method to plot online B-H curves and calculate the core loss of the inductor in a conventional buck-boost power converter is developed. In order to obtain a reliable loss data, measurement error and phase shift error are analyzed and then ...

Low-loss AlInN/GaN microwave switch

Electronics Letters, 2011
A report is presented on the first low-loss monolithic microwave integrated circuit switch using AlInN/GaN heterostructure field effect transistors. Owing to significantly lower sheet resistance compared to the conventional AlGaN/GaN heterostructure (215 against 280 Q/□), and lower contact resistance (0.27 against 0.5 Ω×mm), the microwave switch based ...

Loss Jump During Loss Switch in Solving PDEs with Neural Networks

Communications in Computational Physics
Using neural networks to solve partial differential equations (PDEs) is gaining popularity as an alternative approach in the scientific computing community. Neural networks can integrate different types of information into the loss function. These include observation data, governing equations, and variational forms, etc.

Stability of solitons in PT-symmetric couplers [PDF]

, 2011
Families of analytical solutions are found for symmetric and antisymmetric solitons in the dual-core system with the Kerr nonlinearity and PT-balanced gain and loss. The crucial issue is stability of the solitons.

Non-volatile Optical Switch Based on a GST-Loaded Directional Coupler [PDF]

, 2018
We present a non-volatile optical switch based on a directional coupler comprising a silicon-Ge2Sb2Te5 (GST) hybrid waveguide. The non-volatility of GST makes it attractive for reducing static power consumption in optical switching.
