Abstract: The global electrical energy consumption is steadily rising. To meet the growing demand of electricity and reduction of greenhouse gas emission has prompted renewed interest in the renewable energy system. The cost of renewable energy technologies is on a falling trend and is expected to fall further as demand and production increases. Among various possibilities, the solar cell is an instinct source of energy, which is increasingly being studied, researched and for conversion of electrical energy. In this paper we have studied dc to ac conversion technique using boost inverter with solar energy stored via PV cells in a battery as input. In this way we have enabled to convert 12V dc to 220V ac for home applications. The overall project has been verified by simulation with OrCAD 15.7 simulation software. This technique supports the use of dc-ac boost inverter technique to feasible solution for solar home application.

Abstract: This paper presents a rotor position estimation technique for a 6/4 switched reluctance machine based on Adaptive Neuro fuzzy Inference System (ANFIS). This technique is applied for modelling the nonlinear rotor position of SRM using the magnetization characteristics of the machine. ANFIS has a strong nonlinear approximation ability which could be used for nonlinear modelling and its real time implementations. In this paper, the best features of ANFIS is utilised to develop the computationally efficient rotor position model θ (I,ψ) for SRM. Mathematical model for θ (I,ψ) using ANFIS has been successfully arrived, tested and presented for various values of phase currents (Iph) and phase flux linkage(ψ) of a non linear SRM. It is observed that ANFIS is highly suitable for rotor position θ (I,ψ) modelling of SRM which is tested to be in good agreement with the training and checking data used for modelling
Keywords: Rotor position estimation model, Adaptive neuro-fuzzy inference system (ANFIS), Switched reluctance machine (SRM), Phase flux linkage.

Abstract:Solar Photo Voltaic (PV) cell is a device which directly converts solar energy into electrical energy by means of photovoltaic effects. Photovoltaic cells are made of semi conductors which generate electricity when they absorb light. PV cells generate electricity by using the renewable energy technology which generates green power. The Photovoltaic industry in India is facing severe shortage of silicon, hence the Government of India is not able to achieve the set targets. The purpose of this research paper is three fold: 1. To bring out the latest innovations to better the performance of PV modules. 2. Reduction of direct manufacturing cost. 3. Improve the conversion efficiency.
