Solar energy is the most low cost, competition free, universal source of energy as sun shines throughout. This energy can be converted into useful electrical energy using photovoltaic technology. Photovoltaic technology is one of the most promising for distributed low-power electrical generation. Converting the sun’s radiation directly into electricity is done by solar cells. These cells are made of semiconducting materials similar to those used in computer chips. Photovoltaic arrays may operate more or less efficiently, depending on their series/parallel configuration. Converters like Buck, Boost and Buck-Boost converters are popularly used for photovoltaic systems. But these converters are limited to low power applications. For PV applications like pumping these converters could do a good job as pumping is carried out at high power. Presently dc–dc converters are required in many industrial applications, to improve the voltage. The grid connected DC-DC converters are used for low input-voltage and high step up power conversion, this paper has successfully developed a high-voltage gain dc–dc converter by input-parallel output-series and inductor techniques. In this paper a novel input-parallel output-series boost converter with dual coupled inductors and a voltage multiplier module. The simulation results are presented by using Matlab/simulink software.
