A study on single phase-shift high- power dual active bridge (dab) converter for PV application

Abstract

The Single Phase-Shift (SPS) High-Power Dual Active Bridge (DAB) converters has been studied. This study investigates the Single Phase-Shift control of the High-Power DAB converter, particularly in PV application. It includes the development of a mathematical model, simulations using MATLAB, and experimental validations. It includes calculations of Output Power with varying Phase Angles and switching frequencies. A PV Array “SunPower SPR-295E-WHT-D” has been used with Irradiance as 1000W/𝑚2 and Temp. 250. A thorough analysis has been done to examine the performance of a DAB when used in PV application scenario and results and data have been found out to learn how power changes with Phase Angle and the optimum operating point has been derived. The operating Switching Frequencies that have been used are 30kHz, 50Khz and 75kHz respectively and the Phase angle is varied from 150 to 1800. Losses have not been considered throughout the analysis carried on in this work.
