Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Tuning Method of Resonant Current Controller With DC Elimination for PWM Rectifiers in Electric Multiple Units

IEEE Transactions on Transportation Electrification, 2020
Current control in electric multiple unit (EMU) pulsewidth-modulated (PWM) rectifiers is crucial for the system’s stable operation and fast transient response. It should not only regulate the sinusoidal current under very low switching frequency but also eliminate dc current avoiding transformer core saturation.

Soft-Switching Current-Source Rectifier Based Onboard Charging System for Electric Vehicles

IEEE Transactions on Industry Applications, 2021
In this article, a novel soft-switching current-source rectifier (CSR) based bidirectional on-board charger (OBC) system is proposed for electric vehicles (EVs) comprising multiple battery sets. Besides the CSR's inherent advantages of higher-quality input voltage waveforms, enhanced short-circuit-current tolerant capability and long lifetime of dc ...

Androgen modulates the kinetics of the delayed rectifying K+ current in the electric organ of a weakly electric fish

Developmental Neurobiology, 2007
AbstractWeakly electric fish such as Sternopygus macrurus utilize a unique signal production system, the electric organ (EO), to navigate within their environment and to communicate with conspecifics. The electric organ discharge (EOD) generated by the Sternopygus electric organ is quasi‐sinusoidal and sexually dimorphic; sexually mature males produce ...
