Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

Advanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

Investigation of capacitor voltage balancing in practical implementations of flying capacitor multilevel converters

2017 IEEE 18th Workshop on Control and Modeling for Power Electronics (COMPEL), 2017
Capacitor voltage natural balancing is an attractive feature of flying capacitor multilevel (FCML) converters. However, with the commonly used phase-shifted pulse-width modulation (PSPWM), the capacitor voltages still can deviate, and active balancing is often required.

Submodule Capacitor voltage balancing of Modular Multilevel Converter

2019 International Conference on Electrical, Electronics and Computer Engineering (UPCON), 2019
A modular multilevel converter (MMC) is one of the latest next generation power electronic converter intended to be most suitable for industrial applications. It is made up of N number of sub-modules (SM) connected in cascaded form for obtaining desired high quality multilevel output voltage waveform.
