Comprehensive Investigation of Promising Techniques to Enhance the Voltage Sharing among SiC MOSFET Strings, Supported by Experimental and Simulation Validations

This paper comprehensively reviews several techniques that address the static and dynamic voltage balancing of series-connected MOSFETs. The effectiveness of these techniques was validated through simulations and experiments. Dynamic voltage-balancing techniques include gate signal delay adjustment methods, passive snubbers, passive clamping...

The Modeling of the Flow Behavior Below and Above the Two-Phase Region for Two Newly Developed Meta-Stable beta Titanium Alloys

Isothermal hot compression tests of two promising new titanium alloys (Ti-10 V-1Fe-3Al and Ti-10 V-2Cr-3Al) are performed using a TA DIL805D deformation dilatometer at temperatures in and above the two-phase α + β region (730–880 °C) at strain rates ranging from 10⁻³ to 10⁻¹ s⁻¹. Results show that the flow...

Introduction of Zener Diodes, JFETs and DMOSTs in a BiCMOS Process and Implementation of OTP Memory

In this research a feasibility study was performed on introducing Zener diodes, junction field-effect transistors (JFETs) and double-diffused MOS transistors (DMOSTs) in an existing silicon 0.25 μm BiCMOS process. As a restriction, no changes to the process were allowed. Lateral polysilicon Zener diodes were designed and optimized for low...

Modeling of Microstructure Development during Hot Deformation and Subsequent Annealing of Precipitates Containing AA6016

Microstructure and microchemistry evolution during hot deformation and subsequent annealing of a commercial Al-Mg-Si alloy were experimentally investigated using electron backscatter diffraction (EBSD) and SEM. Meanwhile, a through-process model framework consisting of the deformation model GIA-3IVM+ and the recrystallization (RX) model CORe was...

Evidence of non-Dzyaloshinskii–Moriya ferromagnetism in epitaxial BiFeO3 films

X-ray diffraction analysis and high-resolution electron microscopy of BiFeO3 films prepared by dc magnetron sputtering on single-crystal LaAlO3 (001) substrates reveal that the films have a highly c-oriented orthorhombic crystalline structure. The magnetic properties of the BiFeO3 films are typical of ensembles of interacting superparamagnetic...

Advanced Breakdown Modeling for Solid-State Circuit Design

Modeling of the effects occurring outside the usual region of application of semiconductor devices is becoming more important with increasing demands set upon electronic systems for simultaneous speed and output power. Analog integrated circuit designers are forced to enter regimes of transistor operation that are close to or within the device...

Zener solutions for particle growth in multi-component alloys

In this paper the Zener theory on precipitate growth in supersaturated alloys for planar, cylindrical and spherical geometries is extended to multi-component alloys. The obtained solutions can be used to check the results from numerical simulations under simplified conditions. Further, the multi-component solutions are used to derive the quasi...
