摘要

本文介绍了一种用于“全直流”连接海上风电场的单向MVDC-HVDC变换器。该变换器结合了基于晶闸管的变换器的低功率损耗和电压源变换器的控制能力，以及低功率电子元件计数。高升压比是通过输入并联输出串联配置实现的。讨论了中频的使用，给出了电感的设计条件。提出了一种控制方案，并通过仿真进行了验证。还观察到变换器的高效率。分析表明，这种基于晶闸管的新型单向DC-DC变换器具有潜在的可行性和优势。

Unidirectional thyristor-based DC-DC converter for HVDC connection of offshore wind farms

This paper introduces a unidirectional MVDC-HVDC converter for ‘all DC’ connected offshore wind farms. This converter combines the low power losses of thyristor based converters and the control abilities of voltage source converters, together with low power electronics component count. A high step-up ratio is achieved by an input parallel output series configuration. The use of medium frequency is discussed and inductance design conditions are given. A control scheme is proposed and validated by simulations. The converter high efficiency is also observed. The presented analysis shows a potential feasibility and benefits of this novel unidirectional thyristor-based DC-DC converter.
