Proposal of Hybrid Discontinuous PWM Technique for Five-Phase Inverters under Open-Phase Fault Operation

Machines, 2023
One of the most common issues in inverters are open-circuit faults (OPF). In this scenario, a proper fault-tolerant technique must be used to improve the motor performance.

Reductive Transformation of ALD TeO₂ into Continuous and Impurity-Free Tellurium Films. [PDF]

Small
Atomic layer deposition forms a conformal TeO2 template that transforms to elemental Te through TeH2 mediated reduction using Te(SiMe3)2 and NH3. The transformation is self‐limiting and yields continuous crystalline Te with oxygen‐free bulk and interface even at ultrathin thicknesses.

Discontinuous Space Vector PWM Strategy for Three-Phase Three-Level Electric Vehicle Traction Inverter Fed Two-Phase Load

World Electric Vehicle Journal, 2020
Discontinuous pulse width modulation (DPWM) strategies are usually adopted to reduce the switching loss and output current ripple of three-phase three-level traction inverters under three-phase load conditions. However, if there is a short circuit in any

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.
