Accurate MRAS Embedded Minimum Copper-Loss Based Controller for WRIG Coupled With Variable Speed Wind Turbine

open access: yesIEEE Access, 2023
Sensorless control of the wound rotor induction generator (WRIG) using the model reference adaptive system (MRAS) technique is an attractive option in wind energy generation schemes. However, the accuracy of MRAS under variable wind speed situations is a

Investigation on the Rotor Voltage and the Rotor Frequency in Wound Rotor Induction Motor by the Slip Change

open access: yesKahramanmaraş Sütçü İmam Üniversitesi Mühendislik Bilimleri Dergisi, 2017
Asenkron motorlarda kayma, senkron devirle rotor devri farkının senkron devre oranıdır. Üç fazlı asenkron motorlarda rotor gerilimi ve frekansının kaymaya bağlı olarak değiştiği bilinmektedir. Yapılan çalışmada rotoru sargılı asenkron motorun statoru yıldız bağlanarak şebeke gerilimi uygulanmıştır.

Perilipin‐2‐Anchored Lipid Droplet‐Targeting Phototheranostics

open access: yesAngewandte Chemie, EarlyView.
This study reports two NIR theranostic dyes, C‐BDP‐OH and C‐BDP‐OMe. C‐BDP‐OMe targets lipid droplets via a dual‐anchoring mechanism with PLIN2, enabling wash‐free tumor imaging. With 62.6% photothermal conversion efficiency, it achieves tumor ablation by downregulating PLIN2, disrupting LD‐mitochondria crosstalk, and triggering apoptosis and ...
