Multistage Zeeman deceleration of metastable neon

, 2011
A supersonic beam of metastable neon atoms has been decelerated by exploiting the interaction between the magnetic moment of the atoms and time-dependent inhomogeneous magnetic fields in a multistage Zeeman decelerator.

Disturbance Rejection Control of Power Conversion System Based on Uncertainty and Disturbance Estimator

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes an Uncertainty and Disturbance Estimator (UDE)‐based dual‐loop control for Power Conversion Systems (PCS). Experiments show the UDE controller reduces response time by over 50% compared to PI control, significantly enhancing disturbance rejection against grid and command variations.

3D Lumped Thermal Model for Compliant Press‐Pack IGBT Submodule in MMC

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
We present a 3D lumped thermal model for compliant press‐pack IGBT submodules in MMCs. The model accounts for double‐sided cooling and thermal coupling, achieving high accuracy and efficiency, making it suitable for real‐time condition monitoring. ABSTRACT The compliant press‐pack IGBT is widely used in modular multilevel converters (MMCs).
