This paper is concerned with the mathematical modeling of a Smart High-Side Power IC. Smart Power ICs are power switches with integrated control and protection functions. On the basis of the full circuit of the Smart Power IC, an equivalent circuit, tailored to the needs of systemanalysis and control design, is introduced and mathematically modeled. This allows to model the large signal behavio...

Multiport DC–DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC–DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the pe...

The era of cloud computing is driving deployments of dense, high bandwidth, high port count network devices whose energy consumption is growing super-linearly. This trend diverges from the objective of power proportional, cloud-scale datacenter and enterprise networks, and implies a looming network power wall that will require re-thinking the design and configuration of networks and network sys...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

we propose a new ring resonator side-coupled m-z interferometer all-optical switch throughthe pumped nonlinear directional coupler. by controlling pump power p to lead the coupler reflectivityr approaching to 1, the resonator finesse will be enhanced dramatically, and then the minimumswitching power in silica-based practice devices can be obtained. as a sample, we use a nonlinearcoupler made by...

State of the arts on guided-wave optical switch arrays are reviewed. In this paper, electro-optic Ti:LiNbO3 devices are mainly described in comparison with crosspoint switch element structures and switch array architectures. Packaging technologies and stability problems are discussed for practical system applications. Recent development on other materials such as semiconductor waveguides, therm...

We report on an electro-optically Q-switched Tb:LiYF 4 green laser pumped by a frequency-doubled optically semiconductor blue laser. The characteristics were studied under wide range of repetition rates from 200 Hz to 50 kHz using KD 2 PO Q-switch. Up 198 µJ pulse energy was obtained with width 248 ns at rate Hz, corresponding peak power 797 W 544 nm.

This paper reports on the first demonstration of aluminum nitride (AlN) piezoelectric logic switches that were fabricated with ultra-thin (100nm) AlN films and exhibit a 1 mV threshold voltage via the body-biasing scheme. The application of a relatively low (< 6 V) fixed potential to the body terminal of a 4-terminal switch has resulted in a repeatable threshold voltage of 1 mV. The nanoswitch ...
