This paper is about an efficient brushless dc (BLDC) motor drive for solar photovoltaic (SPV) Array based application. A positive luo converter is utilized to extract the maximum available power from the SPV array and the LUO converter is designed to operate on Discontinuous Conduction Mode DCM for Improve the PF. The LUO converter feeding the 3-phase supply to the BLDC motor via VSI circuit. Low frequency signals used for trigger the switches. Single sensor used for monitor the speed of the BLDC motor. A Direct Power Perturb & Observe (DPPO) algorithm is proposed to control the maximum power point tracking (MPPT) for a photovoltaic (PV) system. The proposed control algorithm eliminates phase current sensors and adapts a fundamental frequency switching of the voltage source inverter (VSI), thus avoiding the power losses due to high frequency switching. No additional control or circuitry is used for speed control of the BLDC motor. The speed control can be achieved through a VSI. An appropriate control of positive luo converter through a Direct power perturb and observe (DPPO) is proposed to control the maximum power point tracking (MPPT) for a photovoltaic (PV) system offers soft starting of the BLDC motor. The proposed system is designed and modelled such that the performance is not affected under dynamic conditions. The suitability of proposed system at practical operating conditions is demonstrated through simulation results using MATLAB/Simulink followed by an experimental validation.

Generally high voltage boost gain cannot be achieved in conventional step-up converters since the parasitic parameters will set an upper limit on the duty ratio at which the converter can efficiently operate. In recent years many high step-up DC-DC converters have been proposed. Among the developed converters, the high step-up single switch converters exhibit large input current ripple which make them unsuitable to operate at heavy load due to high conduction losses. So a new super boost converter is designed. This converter consists of switched capacitors and two coupled inductors. This combination of coupled inductors and switched capacitors can provide high voltage boost gain while operating with small duty cycle. By using one individual DC voltage source in an interleaved manner the converter can be powered. The configuration of the proposed converter advantages such as low power losses, longer lifetime of input sources due to non-pulsating input current, low voltage stress across the main switches and slow output fluctuation. The concept is to constant voltage By implementing this converter a 22.5 times gain can be reached 0.5 duty ratio and turns ratio equal to 2.Simulation results will be presented to demonstrate the authenticity of the proposed converter.

The current system in operation uses sensors which are very expensive and not very sensitive and also uses a good deal of power. The chemical sensor used here is less expensive and efficient also.

Authenticated key exchange is one of the most important applications in applied cryptography, the user interacts with a server to set up a session key to pre-registered information, authentication factor, like password or biometrics of the user is stored. Single-factor AKE is widely used in practice. Higher security concerns call for MFAKE schemes, e.g. combining passwords, biometrics and device simultaneously. Casually designed schemes, security is even weakened in the sense that leakage of one authentication factor will defeat the whole MFAKE protocol. An inevitable by-product arises that the usability of the protocol often drops greatly. To summarize, the existing multi-factor protocols did not provide enough security and efficiency simultaneously. It proposes a very efficient MFAKE protocol. It defines the security model and gives the according to security analysis. It also implements our proposed method as textual, graphical, biometric and device password to access the user accounts. The theoretic comparisons and the experimental results show that this scheme achieves both security and usability operating conditions is demonstrated through simulation results using MATLAB/Simulink followed by an experimental validation.

Solar energy is a promising alternative energy source for a sustainable pollution-free future. But certain factors such as solar irradiation, lack of sunlight during night hours etc. degrade or diminish the scope of solar power. To address with this problem MPPT technique is used here. Due to the requirements of high efficiency, reliability, power density and low cost and reduced size, transformerless PV inverters can be utilized in a grid-connected solar energy system. But the presence of transformerless system will lead to leakage currents, which is not at all acceptable in the case of grid connected applications. So to reduce leakage currents the modified version of H6 inverters ie an H8 inverter is used in this paper. In order to synchronize H8 inverter and grid PI controllers are used. This paper aims to utilize solar energy and reduce the leakage currents produced by transformerless inverter for grid connected applications. This is done by the integration of solar, transformerless step-up converter and h8 inverter. The concept is to utilize renewable sources effectively which helps in reducing the grid demand.
