Performance Analysis of Non-Ideal DC-DC Positive Output Elementary Superlift Luo Converter

Abstract

The increased applications of Power electronic DC to DC converters in various domestic and industrial applications require attention to assess the performance characteristics of converters. The various performance indices of the converters are power transfer efficiency, high voltage gain, low cost, low weight, simple circuitry, and high-power density There are so many power converter topologies which include isolated and non-isolated converters. The isolated converters are compact in size, low weight, economical cost, and minimum losses. In the conversion stages, there are voltage building techniques developed which include voltage lift and super lift techniques. In voltage lift technique, the voltage increases stagewise in arithmetic progression, however in the super lift technique the increase of voltage follows the geometric progression. This results into an increase in the voltage gain of super lift Luo converters largely and so it can be employed in the applications which need the high voltage. In this paper, the Non-ideal POESLL converter is considered, and its performance is analyzed concerning its voltage gain. The performance of POESLLC with and without implementation of PI control has been successfully simulated and verified using MATLAB simulation
