Abstract— Multilevel inverters have gained importance in medium voltage and high power drives applications due to superior performance over two level inverters such as lower harmonics, less voltage stress, better harmonic profile, reduced dv/dt stress, produce lower common mode voltage etc., This paper focuses on implementation of Space Vector Pulse Width Modulation (SVPWM) Technique for Three ...

In this work, we present an original model to explain the accelerated wear-out behavior of irradiated ultra-thin oxides. The model uses a statistical approach to the breakdown occurrences based on a nonhomogeneous Poisson process. By means of our model, we can estimate the number and the time evolution of those damaged regions produced by ion hits that generate breakdown spots during high field...

The purpose of this work is to establish the critical surface conditions leading to the initiation of stress corrosion cracks on the as supplied surfaces of three unidirectional Eglass/polymer composites with modified polyester, epoxy and vinyl ester resins subjected to a nitric acid solution without mechanical loads. The composite materials considered in this study are commonly used in composi...

For the deficiencies of traditional stress detection methods for steel strips in industrial production, this paper proposes a non-contact stress detection scheme based on the magnetoelastic effect. The theoretical model of the transmission-type stress detection is established, in which the output voltage and the tested stress obey a linear relation. Then, a stress detection device is built for ...

The static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. Two engineering cases including cantilever and double cantilever micro-beam are considered. Considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent Euler-Bernoulli beam model is used based on a modified couple stress theory, c...

I. Introduction By reducing the gate-oxide thickness (T OX), the proportion of injected tunneling carriers increases during stress so that MOSFET's parameters are slightly changed. In thicker oxides (T OX >3.5nm), Stress Induced Leakage Current (SILC) was a good marker of oxide degradation. In thinner oxide, gate oxide leakage current appears in depletion regime, SILC is recalled as Low Voltage...

We present measurement results in form of threshold voltage drift plots, recovery traces and continuous capture emission time maps (CET maps) including Negative Bias Temperature Instability (NBTI) and HotCarrier driven Degradation (HCD). The measurements were performed on a 130 nm MOS transistor technology which is used for automotive and analog applications and has a nominal voltage of 1:5 V. ...

Actuator materials can directly convert different types of energy into mechanical energy. In this work, we designed and fabricated electrothermal air pump-type actuators by utilization of various nanostructured carbon materials, including single wall carbon nanotubes (SWCNTs), reduced graphene oxide (r-GO), and graphene oxide (GO)/SWCNT hybrid films as heating elements to transfer electrical st...

This thesis investigates packaging effects on precision bandgap voltage references used in LTC switching regulators. Packaging stress causes a mean offset and room temperature distribution widening of the bandgap reference output voltage, as well as inconsistent temperature characteristics. Bandgap references with and without a proprietary stress-relief mechanism were compared to determine the ...

Received Feb 14, 2017 Revised Apr 14, 2017 Accepted Apr 28, 2017 This paper proposes maximum boost control for 7-level z-source cascaded h-bridge inverter and their affiliation between voltage boost gain and modulation index. Z-source network avoids the usage of external dc-dc boost converter and improves output voltage with minimised harmonic content. Z-source network utilises distinctive LC i...
