The operation and efficiency of HEV (hybrid electrical vehicle) greatly depends on its charging system. The HEV uses grid power to charge the battery. The traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated charger. Most charges are non isolated type having low charging power capacity. Therefore on board isolated high power charger is required for PHEV (plug in hybrid electrical vehicle) which may improve the charging efficiency of the battery. The size and price are important considerations for such integrated charger. In this paper, an integrated on board charger is proposed which provides high charging power and unity power factor operation. In the proposed design, asynchronous machine and bi directional converter are used so that the machine can act as motor during traction and isolated transformer during charging. The boost converter topology is used for the bidirectional converter which can be used as inverter during traction. The proper operation of integrated charger greatly depends on grid synchronization and controlling mechanism of converter and asynchronous machine. The Park transformation is used for mathematical electromechanical model of the asynchronous machine. A controller scheme is designed by using the concepts of conventional controlling scheme of IPM (induction permanent magnet) motor/generator set and decoupled current control method of boost converter. The whole system is simulated in Matlab/Simulink based model in order to verify the system operation of the proposed charger. The simulation results show good performance of the charger leading to machine speed stability and smooth grid synchronization.

The rapid depletion of fossil fuel resources and environmental concern has given awareness on generation of renewable energy resources. Among the various renewable resources, wind energy seems to be promising solution to provide reliable power supply with improved system efficiency. As wind turbine output is proportional to the cube of wind speed, the wind turbine generator output fluctuates due to wind speed variation. This study investigates the influences of a new pitch controller & governor control system model on frequency of power system, when variable load has been considered. It is observed that system frequency can be maintained in acceptable level by using newly designed pitch controller & governor control system when several interconnected synchronous generators (SGs) are operated in different governor control modes with high wind power penetration, when the total capacity of SGs is considered as 100 MVA. Real wind speed data have been considered for this study. PSCAD/EMTDC software is used for simulation analyses.

This paper deals with the injection of reactive power, which is vitally important in case of too much load variations, by means of Static VAr Compensator (SVC) so that both, the voltage profile and voltage stability of the power system can be improved. The reactive power management is formulated as an optimization problem that can be solved by the evolutionary advanced optimization algorithms. Two well known algorithms, namely linear algorithm and genetic algorithm are applied in this case and it has been found that the genetic algorithm gives more efficient outputs compared to the linear algorithm as it is based on the biological metaphor, in which best individuals are selected among parents and offspring generation. As far as this paper is concerned, 0.2 MVAR reactive power would be enough for voltage compensation and maintaining stability throughout the system.

In this paper, a new probability based fast inter mode decision algorithm is proposed for H.264/AVC video standard. The main idea is to classify the inter modes into large and small modes category and determine which one is suitable for a macroblock (MB). Depending on this, the probability of each large mode corresponding to the initial Hadamard SAD16×16 cost or the probability of each small mode corresponding to the initial Hadamard SADs8×8 cost is determined. Then the best mode can be obtained from their probability characteristics. Thus, it is possible to determine the best inter mode only by calculating the Hadamard Transform (H-SAD) cost instead of rate distortion cost. Moreover, it avails the platform to determine the best mode without comparing the cost of each mode to other modes. As a result, this approach can avoid most of the complex computation processes like quantization, variable length coding, pixel reconstruction etc. The experimental results have shown that the proposed algorithm can reduce 60% to 65% of the total encoding time of H.264/ AVC with negligible distortion.

This paper features the spatial characteristics of the brain towards brain-computer interface (BCI) research. A study on motor imagery (MI) based BCI has been carried out and important implications are identified. Common Spatial Pattern (CSP) is applied to the EEG signals before proceeding to the classification. The primary focus of this research is to utilize the spatial dynamics of the brain to develop BCI with reduced number of electrodes which contribute to the motor imagery tasks with optimal impact. It is observed that computational cost can be reduced drastically by selecting channels from specific regions of interests (ROIs) of the brain without compromising the classification accuracy making BCI efficient. Here, we have reported the best classification accuracies 72.5% and 97.1% which are achieved for two subjects (`av' and `ay', respectively, in the dataset IVa in the BCI competition III) using less number of electrodes.

In this article, we have applied Maxwell-Schrodinger analogy to introduce the idea of electromagnetic metamaterial based band gap in semiconductor regime. We have found a new type of band gap in semiconductor hetero-structures, which is analogous to the spatial average single negative (SASN) band gap in multi-layer photonic crystal. Interestingly, width of such bandgaps is controllable according to designers' will. Perfect tunneling of the propagating stationary states and strong spatial delocalization of bounded electronic states have also been observed, which is electronic analogue of the enhancement of evanescent waves in Pendry's lens. Finally, a multilayer structure has been proposed, which supports band-gap at some energy bands and perfect tunneling at target energy value. As the on-off ratio (step transition from low transmission to high transmission) is very high even if the applied energy is very low, this kind of multi-layer structures can be very useful as future low power electronic device and logic transistor.

Graphene nanoribbons (GNRs) are widely used as a channel of nanoscale based transistor. Now it is investigated in very large scale integration (VLSI) based interconnect system because of its higher degree of conductivity. It is seen that the RLC (resistor inductor and capacitor) equivalent circuit of GNR interconnect system has four important parameters like classical capacitance, quantum capacitance, magnetic inductance and kinetic inductance. These parameters have an important relation with the structure (here width) of GNR. Another important parameter is the resonant frequency which is normally calculated from the RLC model of a system. In this paper we have analyzed these four parameters for varying width of GNR. Then the resonant frequency response of GNR based interconnect system has been observed by varying width of GNR. Moreover, we have analyzed our work on resonant frequency by considering the two degeneracy factors of quantum capacitance.

In this paper a new technique is proposed to improve the performance of the linear permanent magnet generator (LPMG) which is basically a point absorber. This paper also represents analysis, design and simulation of a LPMG for improvement of oceanic wave energy conversion (WEC). Different output voltage, current and power waveforms of the conventional and proposed LPMG are analyzed, simulated and compared by MATLAB software by constructing mathematical models of WEC, LPMG and output stage. Various parameters like magnitude, wavelength and phase of oceanic wave are observed to make proper simulation by changing different parameters. It is applicable almost all of the point absorbers and offers the great advantage to get relatively more even power distribution which is a major concern for WEC.

The filter is a planar structure composed of parallel coupled lines with reduced length. The dual band filter is developed using the cascaded coupled lines. High isolation between two pass-bands is achieved. Compared to the previous works, the proposed filter has lower insertion loss at 1.5 GHz and 7.5 GHz. A compact size of 15.7 mm × 33.4 mm is achieved for the proposed filter using Arlon DiClad 880 substrate with a thickness of 0.508 mm.
