High-Frequency Transformer Design With Medium-Voltage Insulation for Resonant Converter in Solid-State Transformer

IEEE transactions on power electronics, 2023
A solid-state transformer can directly convert medium voltage to low voltage (e.g., 400 V) with minimized power-conversion stages. The transformer in the dc–dc module not only provides medium-voltage insulation but also significantly affects the power ...

Solid–Liquid State Transformable Magnetorheological Millirobot

ACS Applied Materials & Interfaces, 2022
Magnetically actuated soft millirobots (magneto-robot) capable of accomplishing on-demand tasks in a remote-control manner using noninvasive magnetic fields are of great interest in biomedical settings. However, the solid magneto-robots are usually restricted by the limited deformability due to the predesigned shape, while the liquid magneto-robots are
