Reliability Evaluation of a Modified Y-source Inverter in Photo-voltaic Application

, 2019
Impedance source inverters have many advantages compared with the traditional voltage-source inverters (VSIs) and current-source inverters (CSIs). Among them, the Y-source inverter (YSI) is the most typical topology which can obtain various voltage gains.

Self-Commissioning of Inverter Nonlinear Effects in AC Drives [PDF]

, 2012
The paper presents a novel technique for an accurate identification of the inverter nonlinear effects, such as the dead-time and on-state voltage drops. The proposed technique is very simple and it is based only on a current control scheme.

Comparative Evaluation of Generalized Multicell Impedance Source Inverter for Drives

International Journal of Power Electronics and Drive Systems (IJPEDS), 2014
Voltage-Source Inverter is limited by its only voltage step-down operation. In adding with extra boosting the flexibility is kept active for  the number of  semiconductors which is unchanged, voltage-type Z-source inverter was earlier proposed. These new classes of inverter is generally less sensitive to electromagnetic noises.

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

Advanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Improved design of passive damping for single phase grid‐connected LCL filtered inverter considering impedance stability

IET Power Electronics
Grid‐connected inverters with an inductor–capacitor–inductor (LCL) filter usually require the implementation of damping in the filter to suppress the resonance associated with the filter and hence ensure internal stability.

Optimized damping for LCL filters in three-phase voltage source inverters coupled by power grid

Journal of Modern Power Systems and Clean Energy, 2017
The application of LCL filters has become popular for inverters connected to the power grid due to their advantages in harmonic current reductions. However, the power grid in a distribution system is non-ideal, presenting itself as a voltage source with ...
