发布时间:2018-08-27 06:59
【摘要】:双Buck逆变器(dual buck inverter,DBI)不存在桥臂直通的问题,且功率开关管和续流二极管分离,便于实现续流二极管的最优选取,因此DBI具有可靠性和变换效率方面的优势。但是,传统DBI滤波电感上的电流是半周期正弦波,磁性元件利用率偏低。为了解决这个问题,提出一种三电感DBI(three-inductor DBI,TIDBI),通过从原始的电感中分离出一个交流滤波电感作为主导的滤波电感,并将两个直流滤波电感耦合,从而提高磁性元件的利用率,有效地降低了滤波电感的体积和重量。详细分析TIDBI的工作原理,给出滤波电感的设计原则。最后通过实验结果验证理论分析的正确性。
[Abstract]:The double Buck inverter (dual buck inverter,DBI) does not have the bridge arm through problem, and the power switch tube and the continuous current diode are separated, which is convenient to realize the optimal selection of the continuous current diode, so DBI has the advantages of reliability and conversion efficiency. However, the current on the traditional DBI filter inductor is half-period sine wave, and the utilization rate of magnetic element is low. In order to solve this problem, a three-inductor DBI (three-inductor DBI,TIDBI) is proposed. By separating an AC filter inductor from the original inductor as the dominant filter inductor, and coupling the two DC filter inductors, the utilization ratio of magnetic components is improved. The volume and weight of the filter inductor are reduced effectively. The working principle of TIDBI is analyzed in detail, and the design principle of filter inductor is given. Finally, the experimental results verify the correctness of the theoretical analysis.
