摘要

双向dc-dc变换器广泛应用于需要双向潮流的应用中。如何对变流器进行更合理的控制，如何对变流器进行更简单的建模和分析，仍是一个有待研究的课题。本文比较了不同的双向dc-dc变换器小信号建模方法。利用PSIM仿真软件中的数学平均小信号建模和交流扫描工具获得变换器的交流响应。用波德图对这些结果进行了比较，以评价建模技术的准确性和方便性。给出了分步计算和仿真，并对仿真结果进行了详细比较。

Comparison of different small signal modeling methods for bidirectional DC-DC converter

Bidirectional dc-dc converters are widely used in applications requiring bidirectional power flow. Control of these converters in a more suitable way and modeling and analyzing of them in a simpler method is still a research topic. In this paper different small signal modeling methods for bidirectional dc-dc converters are compared. Mathematical averaged small signal modeling and ac sweep tool on PSIM simulation software are used to obtain ac response of the converter. These results are compared in terms of bode plots to evaluate accuracy and convenience of the modeling techniques. Step-by-step calculations and simulations are presented together with detailed comparison of simulation results.
