Abstract

This paper present solar energy is most useful for sustainable development. The most important application field of this research is renewable energy resources. Solar energy is being popular ones owing to abundant, ease of availability and convertibility to the electric energy. A general model of Photovoltaic system with proposed Cuk converter is implemented on Matlab such that it gives constant and stepped up dc voltage to the load. A Cuk Converter is used for examine the performance of solar PV system.

Introduction

Solar energy demand is increasing day by day due to increase in population, urbanization, and industrialization, renewable energy resources are alternatives to our traditional energy sources which are limited and will expire. The photovoltaic energy effect can be considered an essential sustainable resource because of solar radiant energy abundance and the sustainability thus grid connected photovoltaic system is widely used, although solar energy is available abundantly and free of cost, the cost of the photovoltaic cells is very high. Hence the initial investment on solar energy will be very high.

Conclusion

This paper analysis nonlinear, switched, and state-space models for CUK converters. The simulation environment MATLAB/SIMULINK is quite suitable to design the modelling circuit, and to learn the dynamic behaviour of different converter structures in open loop. CUK converter, the duty cycle is varied and corresponding voltage and current is observed. It is used different duty cycle, the performance of convertor is better results.
