Theoretical and Simulation Analysis of First Generation DC-DC Converters

Abstract

This paper deals with the question about the most efficient and less energy consumptive type of low voltage DC-DC converter. Different types of DC-DC converters from the first generation are analyzed in terms of voltage transfer capability and output voltage ripple. The comparison of voltage ripple of different types of converters is given. Based on the simplicity, four DC-DC converters namely, Boost converter, Elementary Positive Output Luo Converter (EPOLC), Enhanced Self-Lift Luo Converter (ESLLLC) and Super-Lift Luo Converter (SLLC) are filtered among first generation and their performance for different conduction duty are theoretically analyzed. The theoretical analysis results in the identification of best DC-DC converter, which is suitable for process automation.  Further, the simulink models for those DC-DC converters are developed using MATLAB software. The results on output DC voltage validates that the SLLC is well suitable for the application involving process automation.
