Abstract: An AC/DC hybrid power supply system is proposed, which provides an intelligent power supply platform for distributed power generation. It can be compatible with the existing low-voltage power supply system, making full use of the advantages of distributed power generation, meeting the plug and play and local consumption of electric energy. Through the local conversion of DC-DC, the system reduces the process of DC-AC-DC conversion and reduces energy consumption fundamentally. In the output control strategy, the equal current circulation suppression strategy is used to fundamentally eliminate the danger of circulation and optimize the system efficiency. Simulation experiments verify the effectiveness of the method proposed in this paper.
