An assessment of H‐bridge less grid‐tied multilevel inverter with minimum device count and lesser total standing voltage

IET Power Electronics, EarlyView., 2023
An innovative switched‐capacitor‐based inverter is proposed in this article. The suggested converter can produce a five‐level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The effectiveness of the suggested inverter is verified by experimental results using hardware in loop OPAL‐RT OP4510.

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

Advanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

Advanced Intelligent Systems, EarlyView.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...
