Solar energy and wind energy are highly depended on the climate. So, the available power is discrete. Hence two different renewable energy sources could be combined to get a demanded load power. Hence the system is known as a hybrid power system. Instead of several independent converter, in hybrid system multiple input converter have simple circuit and low cost. But multiple input converters have many modes of operation. So the control circuit is complicated. This paper explains an OCC (one cycle control) method for MIC (Multiple Input Converter) which is simple compared to other control methods. The working of OCC is explained in detail. In one cycle control no current regulator is needed and the design in different mode is simple. Thus, control design is simple.

In this paper a new high speed address generator for the dynamic modulation scheme supportive WiMAX deinterleaver design is proposed. The WiMAX can be both fixed and mobile, in this work the mobile WiMAX is given more importance. The mobile WiMAX uses interleaving and deinterleaving techniques in its transreceiver for eliminating the transmission errors. The WiMAX supports QPSK, 16-QAM and 64-QAM modulation schemes for establishing a connection between subscriber and base stations. Deinterleaver has to produce the addresses for these different modulation schemes by performing the inverse operation of interleaving. The address generator in the deinterleaver hinders the performance of the receiver section of the WiMAX system so it has to be optimized to improve the overall performance. In this paper a new ASIC based design has been proposed for the address generator and the design is been modelled in VHDL.

In most earth leakage applications, the detection of a current leakage to the earth is carried out using a current transducer, called a core balance current transformer (CBCT). The phases and neutral conductors pass through a toroidal CBCT. The design procedure of the CBCT is thus a very important aspect in accurately determining an earth leakage. This paper describes an analytical model to design a CBCT for such an application. The algorithm predicts the operating permeability of the core using an iterative method removing the ambiguity brought on by assuming a constant permeability value. A comparison of its effectiveness with a finite element analysis (FEA) and actual test results for a specific material is also compiled.

In a Vehicular Ad Hoc Network (VANET), before reaching a potentially dangerous zone on road, wireless Collision Avoidance (CA) system issues warnings to drivers. Global positioning system can be used to get the vehicle position and which can be shared with other vehicles in the network. In case of emergency not all the vehicle get affected so broadcasting of alert packet is not feasible rather it has to be multicast. Calculating the list of relative vehicles position is depending on the travelling direction, bearing angle and the distance. Recent studies have shown that sparse vehicle traffic leads to network fragmentation which poses crucial research challenge for safety application. Hence in this paper we propose a system which will find out the relative position between multiple vehicles by using Great Circle Algorithm. The improvement in VANET connectivity is made by road side unit which will manage all the vehicle information and detect the failure vehicle and calculate the detail of the vehicles that get affected by the failure vehicle and multicast alert packet to identified vehicles. This will avoid the broadcasting problem.

Since energy conservation is one of the important issue now days and making our planet pollution free. For these purposes researchers are suggesting alternatives. Battery fed motor vehicles is one of the emerging option rather than conventional fuel vehicles. Bidirectional DC-DC converters are now mostly used in electric vehicles. The main reason behind this is to operate motor in two quadrants as motoring and regenerative for making efficient operation. Bidirectional DC-DC converter consists of buck and boost converter. During motoring mode energy is supplied through a battery and in regenerative mode battery is charged through a DC link created. This paper primarily gives attention on control strategy used for operation. In this gate complimentary control used to trigger initially turned off switch and divert current through anti parallel connected diode of initially active switch so that main switch can be triggered under zero voltage switching.

Bones are the integral part of human body that shows piezoelectric properties. It means that when mechanical stress or mechanical excitation is applied to human body, this mechanical excitation directly affects the bones in body. Due to this excitation bones produce a current within itself which is a human bone property called as piezoelectric effect also known piezoelectricity. It is ability of certain materials for generating AC voltage when it is subjected to mechanical excitation or vibration. Human bones are made up of piezoelectric material thereby when human comes under mechanical excitation, AC voltage sets up in whole body due to piezoelectric effect in bones. A current starts flowing in all parts of body thereby the aim of our research is to determine the electrical conductivity in human body to establish the maximum voltage of 30-60 volts so that this produced piezoelectric charge could be stored in our designed human electricity sensor device. The major goal of our paper is to find out nature and amplitude of produced electric voltage signal waveform from human body and make it storable.

Deformations in windings can be diagnosed by a reliable and powerful method called sweep frequency response analysis (SFRA). In this work the deviation in the frequency response plots is derived in terms of statistical indicators. Nine statistical indicators have been used for the purpose. These indicators, then, complemented using artificial neural network approach, to derive a useful conclusion regarding the deviation based on the frequency responses. Winding deformation case data along with healthy transformer case data have been used to train a multilayer feed-forward neural network with the backpropagation algorithm. The trained neural network can help an expert to analyse statistical indicators to verify the level of deviation and in turn the level of deformation.

In wireless communication, the broadcast nature of the medium has made information security a very important concern. This nature allows the unauthorized receivers to observe and eavesdrop the signals sent by the transmitter to an authorized receiver if it lies within the transmission range. This paper considers the transmit and receive filter design for multiple input multiple output (MIMO) Gaussian wiretap channel. The optimal transmit filter design requires prior knowledge of the type of filters used at the receivers. Here, we assume that the valid receiver and the eavesdropper employ Zero-Forcing (ZF) criteria at their receivers. We also assume that the transmitter, intended receiver and eavesdropper are equipped with two antennas and channel information is known to all parties. The transmit and receive filters are designed with an objective to minimize the mean-square error (MSE) between authenticated parties, while ensuring that the eavesdropper MSE goes beyond a certain level. Performances of the designed filters are analyzed using numerical simulation.

Electromagnetic welding (EMW) is a solid state impact welding technique in which pulsed electromagnetic field is used for welding electrically conductive work pieces. The technique has become an accepted welding process because it enables to join similar, as well as dissimilar metals, which is very difficult to weld by conventional techniques due to differences in melting points. In EMW process, the input energy is the capacitive energy and the job piece to be welded is placed very close to the electromagnetic coil. The welding is accomplished by impact, when the colliding job pieces are accelerated towards each other by the Lorentz force. The electromagnetic and mechanical properties and parameters of the equipment, tool and the job govern the overall welding process. In this paper a proposed analytical model is investigated and parameters such as magnetic Pressure, magnetic field and Voltage for weld formation is theoretically found and is further validated with data available in the literature & simulation using FEM software.
