Active neutral point clamped converter for equal loss distribution
IET Power Electronics, 2014 Active neutral point is the most attractive inverter topology in many applications such as a photovoltaic system because of the equal loss distribution among switches. This study presents a new single‐phase five‐level active neutral‐point clamped converter topology. It can be applied to achieve optimal total harmonic distortion.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines
Advanced Materials, EarlyView.This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.
