The effects of leakage inductance of the output transformer of a current-resonant parallel converter on the latter's characteristics were studied through simulations and experiments. As a parasitic resonance appears between the leakage inductance and the resonance circuit capacitor during the commutating period of the output rectifying circuit every ...

Feasibility study to use the current transformers as inductive partial discharge sensors
Partial discharge (PD) is the most important factor in gradual insulation deterioration of high‐voltage (HV) power equipment, and then PD trend monitoring is a great issue for their condition assessment. Impulsive high‐frequency PD current/voltage signals can be detected by using electrical sensors, e.g. inductive/capacitive sensors.

Demonstration of 300 kA CHI-startup current, coupling to transformer drive and flux savings on NSTX
Discharges formed by transient coaxial helicity injection (CHI) in the National Spherical Torus Experiment (NSTX) have attained peak currents of 300 kA for the first time. CHI-started discharges are coupled to induction, and ramped up to over 1 MA. Up to

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

LLM‐Integrated Human–Robot Interaction System for Microrobots
This paper proposes an LLM‐based control framework for guiding microrobots using human natural language. This framework can convert the natural human speech into safe and executable command sets for reliable navigation in complex environments. The experimental results show high accuracy and robustness in task performance, demonstrating the potential of
