A Comparative Analysis of a Multilevel Inverter Topology Based on Phase Disposition Sinusoidal Pulse Width Modulation

Engineering Proceedings, 2023
A Multilevel Inverter (MLI) meets the power requirements of most power electronic applications. It can provide an AC supply with better power quality. The higher number of levels in an MLI results in better power quality output.

Minimization of Switching Losses for Diode Clamped Multilevel Inverter

International Journal of Computer Applications, 2012
Multilevel inverters are emerging as a most promising alternative for reducing the harmonics and to achieve highvoltage, high-power capability but switching losses are increased because of increased device count. Many modulation techniques like soft switching techniques, space vector-based PWM techniques or sinusoidal PWM-based techniques were employed

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

An Intelligent Piezoelectric System Integrating Self‐Sensing and Autonomous Operation for Adaptive Vibration Control

Advanced Intelligent Systems, EarlyView.
An intelligent piezoelectric vibration control system integrating self‐sensing, autonomous operation, and adaptive bias‐flip synchronized switching damping (SSD) is developed. The system detects vibration extrema, executes synchronized switching control, and autonomously establishes the bias voltage without external sensing instruments, achieving ...
