Supply Grid Synchronization and Operation of a Filterless Cascaded H-Bridge based Grid Emulator

Steadily increasing requirements for grid connected converters, their growing unit power and output voltage call for flexible high-power medium-voltage grid emulators. Four-quadrant Cascaded H-Bridge (CHB) topology features high output voltage resolution a ...

Quantum-Limited Measurements Using an Optical Cavity with Modulated Intrinsic Loss

Alexander Tagantsev, Sergey Fedorov

We analyze a cavity optomechanical setup, in which the position of an oscillator modulates the internal optical loss. We show that, in contrast to systems with a fixed internal loss, in such a setup, quantum-limited position measurements can be performed a ...

Impact of Fin Width on Tri-Gate GaN MOSHEMTs

Elison de Nazareth Matioli, Jun Ma, Luca Nela, Giovanni Santoruvo, Taifang Wang

In this paper, we present a detailed investigation of the impact of fin width (w(fin)) on tri-gate AlGaN/GaN metal-oxide-semiconductor high electron mobility transistors (MOSHEMTs). As w(fin) is reduced, the threshold voltage (V-TH) increases, which is due ...

Crystal Phase Tuning in Planar Films of III-V Semiconductors

Anna Fontcuberta i Morral, Kirsten Emilie Moselund, Nicolas Tappy

We report on the control of the crystal phase of micron-sized planar III-V semiconductor films grown on top of standard (001) oriented substrates. We achieve this by confining the MOCVD process using SiO2 templates and selecting specific growth planes. We ...

Phase Noise Measurements Of Aluminum Scandium Nitride Oscillators

Luis Guillermo Villanueva Torrijo, Marco Liffredo, Andrea Lozzi

This paper presents the first phase noise (PN) measurements of oscillators based on aluminum scandium nitride (AlScN) resonators. 2-port AlScN contour mode resonators (CMR) operating at 195 MHz arc fabricated. A large pool of Q values (ranging from 150 to ...

Mechanisms of Control Authority by Nanosecond Pulsed Dielectric Barrier Discharge Actuators on Flow Separation

Peter Ott, Pénélope Leyland, Christoforos Skourides, Dimitrios Nyfantis, Hugo Bosse

The mechanisms that should be considered for separation flow control applications of nanosecond pulsed dielectric barrier discharge (DBD) actuators were investigated on a NACA 0015 profile for velocities of 10 m/s (Re = 100, 000) and 20 m/s (Re = 200, 000) ...

Passivity-based Voltage and Frequency Stabilization in AC microgrids

Giancarlo Ferrari Trecate, Pulkit Nahata

In this paper, we investigate the stability of an islanded AC microgrid (ImG) composed of Distributed generation units (DGUs), dynamic power lines, and loads. Each DGU is equipped with a local controller to ensure desired voltage and frequency in the ImG. ...

Coherent Dynamics of Nanowire Force Sensors

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Nicola Rossi

We describe the use of grown nanowires as scanning directional force sensors. Two orthogonal flexural modes are used to demonstrate vectorial sensing of electric and magnetic fields. Furthermore, we show that the modes can be strongly coupled by demonstrat ...
