| 摘 要： | 隔离型双向DC/DC变换器是电力电子变压器(PET)的重要组成部分,其性能好坏将显著影响整个PET的功能.大功率隔离型双向DC/DC变换器多采用模块化串并联的方式实现.设计过程中存在控制复杂、研发周期长、测试困难等问题.本文基于RT-LAB搭建了包含模块化隔离型双向DC/DC变换器实际物理装置的半实物仿真平台,利用RT-LAB的控制功能及在线参数调试等特点对系统进行优化设计.实现了输入串联输出并联型DC/DC变换器均压均流控制策略.结果表明:该半实物仿真平台是研究模块化DC/DC变换器系统的有效方法.

| Abstract: | Isolated bi-directional DC/DC converter is an important part of power electronic transformers,its performance will significantly affect the function of the entire Power Electronic Transformers(PET).Modular series-parallel structure is an effect way to realize high-power isolated bi-directional DC/DC converter,while the challenge of control complexity,testability and long developing cycle exist.A hardware-in-the-loop simulation platform is proposed and implemented on RT-LAB,which includes the physical device of the modular isolated bi-directional DC/DC converter and its control part.The system is optimized with RT-LAB control and online tuning function.The input-series-output-parallel DC/DC converter voltage and current equalization control strategy is realized.The results show that the hardware simulation platform is an effective method in studying the modular DC/DC converter system. |
