Can a three-phase modular converter be used in DC and AC microgrids?

Roncero-Clemente, C. et al. Feasibility study of three-phase modular converter for dual-purpose application in DC and AC microgrids. IEEE J. Emerg. Select. Top. Power Electron. 12 (2), 1348–1358 (2024).

What is AC microgrid?

This is because of well-established ac power networks with compatible modes of electrical and electronic devices. The distribution system of an ac microgrid can principally be classified as one of three types, single-phase or three-phase with/without neutral-point lines.

Is there a universal power conversion mechanism between AC/DC microgrids?

The generic solution proposed in this paper aims to provide a universal power conversion mechanism between DC supply and AC/DC microgrids. Typically, power conversion stages may involve isolated high-frequency stages to ensure efficient and stable operation.

Why do microgrids need a modular power converter?

The modular design of these converters allows for scalability and redundancy, making them suitable for various microgrid configurations. The integration of renewable energy sources, such as solar and wind, into microgrids has also led to the development of novel converter topologies that can efficiently manage power from these intermittent sources.
