Voltage-Sharing Converter to Supply Single-Phase Asymmetrical Four-Level Diode-Clamped Inverter With High Power Factor Loads

, 2010
The output voltage quality of some of the single-phase multilevel inverters can be improved when their dc-link voltages are regulated asymmetrically. Symmetrical and asymmetrical multilevel diode-clamped inverters have the problem of dc-link capacitor ...

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

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

Laser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

A Schottky diode clamped merged drain CMOS structure

Solid-State Electronics, 2002
Abstract A TiSi 2 –Si Schottky diode clamped merged drain (SCMD) CMOS concept is proposed and its initial feasibility is demonstrated by fabricating the structure in foundry 0.8 and 0.5 μm salicide CMOS processes. Output I – V and isolation characteristics of SCMD MOS transistors are almost identical to those of conventional MOS transistors, while ...

Optical Stimulation and Monitoring of the Peripheral Nervous System: Perspectives and Challenges Toward Clinical Translation

Laser &Photonics Reviews, EarlyView.
Optical neuromodulation with IR light allows stimulation of the PNS without the need for physical contact with the target nerve or without requiring any genetic modification. The clinical translation of this technique will pave the way to the development of neural interfaces for restoring sensory feedback in individuals with limb amputation.
