Abstract: In order to accurately cultivate the practical skills of the master’s degree in power electronics and lay the foundation for following research, a multi-port DC micro-grid experimental platform scheme is proposed. On the basis of researching related DC micro-network experimental platform at home and abroad, considering the laboratory environment of general power distribution, the design goal of the experimental platform was established, and the composition, construction and related experiments of the platform were introduced in detail, and the construction process was discussed the training of the master’s knowledge system and practical ability in power electronics. By introducing an effective management mechanism, the ability of independent thinking and teamwork can be cultivated while ensuring the progress of the platform construction. The experimental results show that the system runs stably and the converters in the microgrid have achieved the design goals.
