Active voltage damping method with negative DC link current feedback in electric and hybrid electric transmissions

Научно-технический вестник информационных технологий, механики и оптики
Electric and hybrid electric transmissions in traction drive have a limited capacity power source. Since the traction drive operates in the torque source mode, the DC link voltage becomes unstable and goes into oscillatory mode.

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

Advanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

An Online Condition Monitoring Method for DC-Link Capacitors of Three-Level NPC Inverters Based on Charge–Discharge Profile [PDF]

This article proposes an online condition monitoring (CM) method for the DC-link capacitors of three-level neutral-point clamped (NPC) inverters. A decrease in capacitance typically indicates the degradation of DC-link capacitors.

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

Advanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.
