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.
