Discontinuous space vector pulse width modulation techniques for a five-phase quasi Z-source inverter

, 2015
In this paper, discontinuous space vector pulse width modulation for a five-phase quasi Z-source inverter is presented. Two schemes are introduced for the continuous SVM of five-phase qZSI (SVQ1 & SVQ2) and two schemes of discontinuous SVM (DSVQ1 & DSVQ2)

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

M3D‐DPWM strategy for three‐phase four‐leg inverter with higher harmonic suppression capability

IET Power Electronics
Three‐phase four‐leg inverters are widely used in power systems due to their inherent ability to handle unbalanced loads. However, with conventional 3D space vector pulse width modulation (3D‐SVPWM), high harmonics of large amplitude exist in the output ...

Generalized Pulse Width Modulation Switch Model for Converters Based on the Multistate Switching Cell in Discontinuous Conduction Mode

Sensors
This work introduces a generalized version of the pulse width modulation (PWM) switch model applied in the small-signal modeling of converters based on the multistate switching cell (MSSC) operating in discontinuous conduction mode (DCM).

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Comparative Analysis of Space Vector Pulse-Width Modulation Techniques of Three-Phase Inverter to Minimize Common Mode Voltage and/or Switching Losses

Mathematics
Inverter-based systems encounter significant challenges in mitigating common-mode voltage (CMV) and minimizing inverter losses. Despite various space vector pulse-width modulation (SVPWM) techniques proposed to address these issues, a comprehensive ...

Self‐Powered Broadband High‐Responsivity Photodetectors: p‐(CuS)x(ZnSe)1−x/p‐Si Isotype Heterojunction

Small, EarlyView.
This study reports a self‐powered broadband photodetector based on compositionally tuned p‐(CuS)x(ZnSe)1−x/p‐Si isotype heterojunctions. Increasing the CuS ratio improved the film crystallinity and produced a denser, more homogeneous nanopillar morphology, enhancing light absorption.

Quantitative Imaging of Human Hemoglobin Binding to Staphylococcus aureus With Single‐Molecule Resolution

Small, EarlyView.
Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.
