Comparitive Analysis of Positive Output Elementary Superlift Luo Converter using PI and Fuzzy Controller

The applications of Power electronic DC-DC converters are increasing frequently with the advancement of technology. There are more than 500 topologies of the power converters which are categorized into non-isolated and isolated converters. Selection of converter topology is based on the area of application as well as some important performance parameters such as cost, power density, power transfer efficiency, gain and size. This paper presents the comparative analysis of positive output super lift Luo converter with Proportional-Integral and Fuzzy logic-based controller. The converter is designed under CCM mode, and the modelling of converter is done using state space method. The POSLLC is designed along with two controllers and performance is analyzed and compared for both. This analysis can be utilized effectively for the choice of robust controller with high dynamic performance. The simulation study of converter with both the controllers is executed in the MATLAB platform and the results are compared and illustrated.
