An improved Dual Active Bridge Power Converter for EV batteries

Abstract

The dual active bridges Power converter is indeed a versatile power converter that can be utilized inside a variety of uses. Many studies have been conducted to look at such a conversion from various perspectives. In this research, an optimum DAB converter’s structure is given that provides minimal reactive component while also reducing the weights and sizes of the converters inductors, ensuring the Dc converters step of electric car drive systems. To meet this need while minimizing the converter’s reactive element (circulating current or conduction inefficiencies), dual modes of operation were taken into account: an optimum extended phase shift (EPS) modulations and an ideal triangle phase shifting (TrgPS) modulator. A trajectory tracking controllers are used to control the functioning of the DAB conversion in both states. The DAB converter’s performance with such an application is ideal while running beneath efficient (TrgPS) modulating technique, according to simulated data reported in the study utilizing MATLAB Simulink. It addresses several other difficulties, including such transitory load oscillation and source voltage disruption impacts, and designed for ease of controlling, in addition to the standard characteristics.
