Volume 1, Number 1, June 2010 9 May 2010 Abstract – This paper presents a power loss minimization technique for a cascaded multilevel inverter using hybrid carrier based space vector modulation. The proposal in this paper combines the features of carrier based space vector modulation and the fundamental frequency modulation strategy. The main characteristic of this modulation is the reduction o...

We describe a model of Raman-parametric hybrid amplifier and present its simulation results for flat gain amplification in Dense Wavelength Division multiplexed (DWDM) terabits capacity system. In the proposed configuration single pump FOPA is cascaded after Raman to form a hybrid with each implemented in separate length of fiber. This allows for maximum optimization of gain achieved using Rama...

This paper presents a cascaded H-bridge multilevel boost inverter for electric vehicle (EV) and hybrid EV (HEV) applications implemented without the use of inductors. Currently available power inverter systems for HEVs use a dc–dc boost converter to boost the battery voltage for a traditional three-phase inverter. The present HEV traction drive inverters have low power density, are expensive, a...

-----------------------------------------------------ABSTRACT----------------------------------------------------In recent years, multilevel inverters have gained much attention in the application areas of medium voltage and high power owing to their various advantages such as lower common mode voltage, lower voltage stress on power switches, lower dv/dt ratio to supply lower harmonic contents ...

Wide issue processors with many pipeline stages require e cient branch prediction for high throughput. In this paper, we propose an Embedded, Architecturally Simple and E cient (EASE) branch predictor, which performs well for programs having a small number (100) and a large number (16,000) of instructions. EASE uses a combination of a G-share predictor and a one-level predictor. In EASE, one-le...

This paper presents the hybrid seven-level cascaded active neutral-point-clamped (ANPC)-based multilevel converter. The converter topology is the cascaded connection of a three-level ANPC converter and an H-bridge per phase. The proposed topology provides a tradeoff between different component counts to achieve a good loss distribution, avoid direct series connection of semiconductor devices, k...

In this paper, we propose a robust multilevel fusion strategy involving cascaded fusion of hybrid multimodal fusion of audio-lip-face motion, correlation and depth features for biometric person authentication. The proposed approach combines the information from different audio-video based modules, namely: audio-lip motion module, audio-lip correlation module, 2D+3D motiondepth fusion module, an...
