Guang-Yu Sun, Chao Wang, Haoxiang Zhao
High-voltage and high-power devices are indispensablein spacecraftfor outer space explorations, whose operations require aerospace materialswith adequate vacuum surface insulation performance. Despite persistentattempts to fabricate such materials, current ...
AMER CHEMICAL SOC2023Enablers for Overcurrent Capability of Silicon-Carbide-Based Power Converters: An Overview
With the increase in penetration of power electronic converters in the power systems, a demand for overcurrent/ overloading capability has risen for the fault clearance duration. This article gives an overview of the limiting factors and the recent technol ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Analysis and Design for Medium Voltage Dual Active Bridge Converter Based on Series-Connected SiC MOSFETs
Chengmin Li, Rui Lu, Heng Fang
In this article, a series-connected SiC MOSFETs-based medium voltage (MV) dual active bridge (DAB) converter featuring a lowvoltage difference amongdevices and high efficiency is proposed. In the developed DAB converter, the zero voltage switching-on chara ...
Piscataway2023Metal-wire-embedded alumina insulating material using micro- and nanoscale 3D printing for surface flashover mitigation in a vacuum
A micro- and nanoscale 3D printing technique is applied to fabricate a functional insulating material that mitigates surface discharge in a vacuum based on microscopic electron multipactor suppression. The proposed alumina ceramic insulator design consists ...
2022Design and Manufacturing of an Electrostatic MEMS Relay for High Power Applications
Yves Perriard, Yoan René Cyrille Civet, Christian Köchli, Florian Louis Copt
This paper addresses the design and manufacturing of a crab-leg based MEMS relay for a high power application. Thanks to a contact resistance lower than 100 mΩ, the relay can hold a current in the order of magnitude of an Ampere without further thermal lim ...
2021Fully Soft-Switched High Step-Up Nonisolated Three-Port DC-DC Converter Using GaN HEMTs
Marco Mattavelli, Elison de Nazareth Matioli, Georgios Kampitsis, Rasoul Faraji
In this article, a soft-switched nonisolated high step-up multi-input dc-dc converter is proposed. The proposed converter has overcome the hard switching problem of the conventional boost three port converter (boost-TPC) by providing zero-voltage-switching ...

The broad applications of ultrawide-band signals and terahertz waves in quantum measurements, imaging and sensing techniques, advanced biological treatments, and very-high-data-rate communications have drawn extensive attention to ultrafast electronics. In ...
2020Triboelectric‐TFT Flip‐Flop for Bistable Latching of Dielectric Elastomer Actuators
Danick Briand, Herbert Shea, Rubaiyet Iftekharul Haque, Alexis Pierre Henri Marette, Xiaobin Ji, Ronan Julien Hinchet
A high‐voltage flip‐flop combining two self‐powered soft sensors with a flexible high‐voltage thin film transistor (HVTFT) is reported, and is used to electrically latch dielectric elastomer actuators (DEAs) in zero and high‐strain states. Two touch‐actuat ...
2019Latchable microfluidic valve arrays based on shape memory polymer actuators
Herbert Shea, Nadine Besse, Bekir Aksoy
We report arrays of latching microfluidic valves based on shape memory polymers (SMPs), and show their applications as reagent mixers and as peristaltic pumps. The valve design takes advantage of the SMP's multiple stable shapes and over a hundred-fold sti ...
