摘要

本文提出了一种高效率、高功率密度的多端口DC-AC变换器。该电路由全桥变换器、串联有源滤波器和解压缩电路组成。该电路采用低开关频率的方波运算，降低了开关损耗。此外，与传统的多端口变换器相比，该变换器的电感数量显著减少，从而提高了功率密度。实验结果表明，该电路的最高效率可达99.3%。最后，利用Pareto前曲线对该变换器的功率密度进行了评价。结果表明，该电路的功率密度比传统电路提高了1.6倍。

Development of multi-port converter with square-wave-voltage multilevel converter and active power filter connected in series

This paper proposes a multi-port DC-AC converter with high efficiency and high-power density. The proposed circuit consists of a full bridge converter, a series active filter, and an unfolder circuit. The proposed circuit reduces the low switching losses owing to the square waveform operation with low switching frequency. In addition, the proposed converter improves the power density because the number of inductors is significantly reduced compared to the conventional multi-port converter. As the experimental result, the maximum efficiency of the proposed circuit reached 99.3%. Finally, the power density of the proposed converter is evaluated by the Pareto front curve. As the result, the power density of the proposed circuit was increased by 1.6 times in comparison with the conventional circuit.
