Multilevel inverters have drawn tremendous interest in high power and high voltage application. Multilevel inverters have unique structure which makes it possible to reach high voltages with less harmonic content. The harmonic content of the output voltage waveform decreases as the number of output voltage increases. The main advantages are lower Total Harmonic Distortion (THD), less stress on ...

This paper presents a three level NPC LCswitched voltage source inverter. Conventional multilevel voltage source inverter behaves like voltage step down converter. Recently multilevel buck-boost Z-source inverter (ZSI) has been developed for better efficiency and power quality in renewable energy system. The impedance network of the Z-source inverter requires equal inductors and equal capacitor...

This study investigates the efficacy of optimal semi-active dampers for achieving the best results in seismic response mitigation of adjacent buildings connected to each other by magnetorheological (MR) dampers under earthquakes. One of the challenges in the application of this study is to develop an effective optimal control strategy that can fully utilize the capabilities of the MR dampers. H...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

Bacterial porins are water-filled β-barrel channels that allow translocation of solutes across the outer membrane. They feature a constriction zone, contributed by the plunging of extracellular loop 3 (L3) into the channel lumen. Porins are generally in the open state, but undergo gating in response to external voltages. To date the underlying mechanism is unclear. Here we report results from m...

In this paper we show that in modern computing systems, DVFS gives much more limited energy savings with relatively high performance overhead as compared to running workloads at high speed and then transitioning into low power state. The primary reasons for this are recent advancements in platform and CPU architectures such as sophisticated memory subsystem design, and more efficient low power ...

Parameter variations have become a dominant challenge in microprocessor design. Voltage variation is especially daunting because it happens rapidly. We measure and characterize voltage variation in a running Intel R © CoreTM2 Duo processor. By sensing on-die voltage as the processor runs single-threaded, multithreaded, and multi-program workloads, we determine the average supply voltage swing o...
