摘要

与前对前(F2F)拓扑结构相比，DC/DC自耦变压器具有几个优点。这项工作提出了无变压器(TL) DC/DC自耦变压器拓扑结构，它包括用交流滤波器代替DC/DC自耦变压器中的交流变压器，目的是降低其成本。对TL拓扑进行了建模，给出了其控制方法，并通过仿真验证了其运行效果。此外，还估计了变流器在部分和全部负载下的损耗。

Transformerless DC/DC converter based on the autotransformer concept for the interconnection of HVDC grids

DC/DC autotransformers present several advantages compared to Front-to-Front (F2F) topologies. This work presents the Transformerless (TL) DC/DC autotransformer topology, which consists on the substitution of the AC transformer in the DC/DC autotransformer for an AC filter, with the objective of reducing its cost. The TL topology is modelled, its control presented and its operation validated by means of simulations. Also, the losses of the converter are estimated for partial and full load.
