Microgrids can be grouped into 2 types: AC and DC, depending on the main bus for supplying the load. When hybrid microgrids, AC and DC types are physically separated by the location, but near by, a bidirectional converter is required to connect and to transfer the power to each other. This study proposed a bidirectional converter system for connecting AC and DC microgrids. The converter transfers power from the surplus microgrid to the lack one. It also converts dc power from the microgrid to ac power of the other microgrid and vice versa. This control arrangement is used to improve the system performances. Some simulations to a hybrid AC-DC microgrid had been done in four different cases. Every simulation had gained result for bi-directional converter performance to maintain stable system operation under various load and resource condition.
