Abstract
The increasing integration of the solar based system, EV's(Electrical vehicles) with the existing conventional generation has led to required dc-dc converters for interfacing. For improve the system performance the DC-DC converters have to meet many requirements, such as high energy density, less ripple in the system, low EMI(Electromagnetic interference), compact size. Hence, a DC-DC interleaved CUK converter (ICC) is most suitable choice for meeting the requirements. This paper is based on the novel idea of modeling and controlling an interleaved CUK converter. Modeling is carried by linearizing the nonlinear model of the converter via average and small signal modelling and tuning of controller parameters is based on heuristic search technique known as Genetic Algorithm. The results show a better response time (rise time, settling time) and error specification in case of GA tuned controller than without controller. Hence, it can be concluded that this element (converter) coupled controller can give the desired results as demanded by the energy device.
