摘要：

The subject of the article is the design of a prototype of a two-level three-phase grid converter with a rated power of 15 kW and a DC voltage of 760V. The goal was to verify the control algorithm of the two-level AC/DC converter in the experimental system. The algorithm enables the use of the converter in a DC microgrid. The efficient hybrid controller used in the system enables the use of an advanced control algorithm. The tested converter and the control algorithm used allow for direct control of active and reactive power in bidirectional operation. Immunity to voltage distortion and changes in its frequency was obtained by the synchronization module with the network (DSOGI-PLL). The paper presents the results of simulation and experimental studies.
