This paper presents cost effective hardware realization of back propagation neural network for DC- DC Converter. Artificial neural network (ANN) has become very popular in many control applications due to their high speed operation in real time applications which can be achieved if the networks are implemented using parallel hardware architecture. To achieve these parallelism, modularity and dynamic adaptation of ANN, reconfigurable Field Programmable Gate Array (FPGA) is used which offer flexible designs, savings in cost and design cycle. The training patterns for the neuron controller were obtained from the synergetic controller which is implemented in simulink and the designed neural network controller was implemented in FPGA using Very High Speed Integrated Circuits (VHSIC) Hardware Description Language (VHDL). The simulation was done by using MATLAB and Xilinx ISE software.

Inverters are used in solar photovoltaic (PV) system to convert the D.C power produced by the solar photovoltaic cell into AC. This paper presents a novel Adaptive Hysteresis Current Controller to control the inverter used in the solar photovoltaic system. The proposed controller is capable of reducing the total harmonic distortion and to provide constant switching frequency. The mathematical model of Photovoltaic array is developed using Newton’s method. The modeled Photovoltaic array is interfaced with DC-DC boost converter, AC-DC inverter and load. A DC-DC boost converter is used to step up the input DC voltage, the inverter converts the DC voltage into AC. The inverter is controlled by the proposed current controller. The performance of the proposed controller is evaluated through MATLAB/Simulation. The results obtained with the proposed algorithm are compared with those obtained when using conventional fixed hysteresis current controller in terms of THD and switching frequency.Keywords

Now-a-days peoples are health conscious and are looking forward to have products that carry functional and therapeutic values. Aloe vera (Aloe barbadensis miller) is such a plant that has as many as 200 different types of moleculesof health importance. Due to this, it has been used since ancient time for treating various types of disorders. The Aloe vera contains 1.0-1.5 per cent TS out of which, polysaccharides occupy 55 per cent, sugars 17 per cent, minerals 16 per cent, proteins 7 per cent, lipids 4 per cent and phenolic compounds 1per cent on dry basis. It also contains many vitamins A, C and E. Vitamin B1 (thiamine), niacin, Vitamin B2 (riboflavin), vitamins B12 (cyanocobalamin), choline and folic acid including the important antioxidant. Health benefits of Aloe vera include wound healing, halts the cancer tumors, prevents kidney stones, lowers high cholesterol, reduces high blood pressure, stabilizes blood sugarand ends constipation. These days researchers are also concentrating to utilize Aloe vera as an ingredient in dairy and food formulations. Aloe vera gel or juice are used to incorporate in different dairy products like flavoured milk, ice cream, Dahi, yoghurt, Lassi and also food products like RTS and edible coatings etc.
