Abstract

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

Highlights

In recent decades, high frequency and high-power DC-DC converters have been used because of their outrageous results and significance in a few regions of the energy sector such as distribution grids, renewable energy sector, energy storage system electric vehicles, and data centers
The SAB3 shown in Figure 1 is the unidirectional version of the well-known high-power density bidirectional Dual Active Bridge (DAB) for high power applications
In order to compare the performance of SAB3 when connected through various vector group of transformers, first it is simulated

Summary

Introduction

High frequency and high-power DC-DC converters have been used because of their outrageous results and significance in a few regions of the energy sector such as distribution grids, renewable energy sector, energy storage system electric vehicles, and data centers. SAB3 converter due to its compact size and attractive features, is used in high power applications such as high voltage direct current (HVDC), photovoltaic systems, and wind turbines. Harmonics generated due to the switching of solid-state switches in the SAB3 when it operates over a large voltage and load range at a constant frequency, for a specific application, a specific vector group gives optimum results [4]. There are various studies on harmonics mitigation that are found in literature which analyzed the performance and the impact on power quality when linked with SAB3 through three-phase power transformer [7]. Harmonics generated by different nonlinear utilities are different, for a specific application, a specific vector group would give optimum results. Due to the switching of power devices in three-phase inverters, the harmonics are generated and when these
