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.

“…The multiple-primary-side series-connected winding transformer, as a special transformer structure, is mainly utilized in high-power systems [25][26][27]. Compared with the multiple-split winding transformer, a lower short-circuit impedance of the multiple-primary-side series-connected winding transformer can be designed but with the same current THD.…”

High-power three-level voltage-source converters are widely utilized in high-performance AC drive systems. In several ultra-power instances, the harmonics on the grid side should be reduced through multiple rectifications. A combined harmonic elimination method that includes a dual primary-side series-connected winding transformer and selective harmonic elimination pulse-width modulation is proposed to eliminate low-order current harmonics on the primary and secondary sides of transformers. Through an analysis of the harmonic influence caused by dead time and DC magnetic bias, a synthetic compensation control strategy is presented to minimize the grid-side harmonics in the dual primary side series-connected winding transformer application. Both simulation and experimental results demonstrate that the proposed control strategy can significantly reduce the converter input current harmonics and eliminates the DC magnetic bias in the transformer.
