The speech features used for speaker recognition should uniquely reflect characteristics of the speaker's vocal tract apparatus and contain negligible information about the linguistic contents in the speech. Cepstral features such as Linear Predictive Spectral Coefficients (LPCCs) and Mel Frequency Cepstral Coefficients (MFCCs) are most commonly used features for speaker recognition task, but found...
The concerns for environment due the ever increasing use of fossil fuels and rapid depletion of this resource have led to the development of alternative source of energy such as solar energy. This paper proposes that how to increase the efficiency of a solar PV energy system by the advancement in conventional DC to DC Boost converter. This paper also proposes the study of open loop systems with elevated...
This paper presents a comparison analysis between two engineering software platforms, Matlab/Simulink & PSIM, which are used as major educational tools in the teaching of power electronics and electrical drive courses, in additional to conducted research in these fields. The comparison analysis is based on studying the design simplicity of the module, time consumed in building of the module, accuracy,...
This paper describes the application of the Single Input Fuzzy Logic Controllers (SIFLC) to regulate the output voltage of a Boost (step-up) DC to DC power converter. The SIFLC is derived from the Signed Distance Method which reduces the multi-input Fuzzy Logic Controller (FLC) with Toeplitz rule table structure to a single input FLC. Effectively, it allows for the rule table to be approximated to...
Wind energy conversion systems is now occupying important space in the research of renewable energy sources. There is a need for more research on wind generators, power converter topologies etc. In this paper behavior of wind generator have been studied in MATLAB. Generator used here for study is permanent magnet synchronous generator (PMSG). This paper also provides comparison of different power...
Fuel Cell (FC) is one of the promising distributed generation resources which are based on renewable energies. Clean electricity generation, high efficiency and high energy density of the fuel cells make them attractive for lots of engineers. In this paper we discuss about the operational principles of fuel cell generally. Then, a circuit model of them will be introduced. Based on the model, we designed...
The paper proposes a novel power conversion system for universal and flexible power management (UNIFLEX-PM) in future electricity network. The structure is based on three AC-DC converters each one connected to a different grid, (representing the main grid and/or various distributed generation systems) on the AC side, and linked together at DC side by suitable DC isolation modules. Each port of the...
The main issue of this work is to analyze and to test how the characteristic curve of the induction machine can be adjusted by the power electronic devices, when these are integrated into rotor circuits. In order to technically analyze the characteristic performances of the induction machine by switching between cages, the simulator software's MATLAB and NETASIM have been used. The simulated current-...
A hybrid multilevel inverter model based on PSIM and MATLAB/SIMULINK is presented in this paper. It consists of a standard 3-leg inverter (one leg for each phase) and H-bridge in series with each inverter leg. The inverter can be used in hybrid electric vehicles (HEV) and electric vehicles (EV). The co-simulation model is employed in order to take full advantage of different power electronics simulation...
