Abstract

In this paper, an integrated coupled-inductor is proposed to achieve both current and voltage balancing for parallel-connected triple-active-bridge (TAB) converters. For the parallel connection of modular converters, a dedicated current balancing scheme is required to address the unbalanced current of each module. Furthermore, the TAB converter is composed of two loads and the discrepancy of each load can cause an imbalance of output voltages. The proposed coupled-inductor can achieve both current and voltage balancing performance under the aforementioned conditions without any additional passive or active components. The balancing technique is experimentally verified through a 4-kW laboratory prototype.
