Abstract

This paper introduces a systematic methodology to develop a unified model for a multi-port Triple Active Bridge (TAB) converter. The proposed model accurately predicts the AC port currents in a TAB converter. The model can be used to compute performance metrices of the TAB converter such as the peak and RMS currents at the AC ports, and the average currents at the DC ports. One of the features of the proposed model is that it can predict the impact of transformer magnetizing inductance on the AC and DC port currents. The proposed model is valid for all operating modes and modulation strategies of the TAB converter. The accuracy of the model has been verified against extensive switching circuit simulations for a variety of operating conditions. Experimental results from a TAB converter laboratory prototype are also presented to showcase the impact of magnetizing inductance variation on TAB converter performance.
