Comparative Analysis of Three-Phase Single Active Bridge DC-DC Converter with Different Mode of Conduction with Transformer Vector Groups

Abstract

Background/objectives: This research study compares the performance of a three-phase single active bridge DC-DC converter with several operating modes along with vector groups in order to present the importance and applications of transformer vector groups in the electrical network system.

Methods/statistical analysis: In order to analyze and compare the operating characteristics of three-phase single active bridge converter with vector groups of transformer. Initially, we made a detailed study of vector groups of transformers through literature review. Then the development of simulation model of three-phase single active bridge DC-DC converter with transformer vector groups while operating with different operating modes of three-phase inverter by using MATLAB/SIMULINK software was made.

Findings: We investigated Total Harmonic Distortion (THD) in terms of voltage and current waveforms with both resistive and inductive load of SAB3 converter with the different transformer vector group while operating with different modes of conduction, i.e., 120, 150, and 180.

Improvements: Undoubtedly, today’s world is moving towards replacing fossil fuels with renewable energy resources. Three-phase single active bridge DC-DC converters are widely advantageous. From the simulated results, it is clear that at 150-operating mode, the SAB3 generated fewer harmonics in terms of voltage and current for both resistive and inductive load as compared to other operating modes.

Keywords: DC-DC Converter, Harmonics, Total Harmonic Distortion (THD), Three-Phase Single Active Bridge DC-DC Converter (SAB3).
