With the increasing of distributed energy sources, AC-DC hybrid microgrids have attracted more and more attention as an effective means for efficient use of distributed energy. The bidirectional power converter is the core of energy control in hybrid AC/DC power grids and has been widely studied and utilized. Firstly, the relevant basic knowledge was introduced, including PWM control method, d-q transform and PI control. Second, the prototype of the converter was constructed to realize bidirectional power flow, and an experiment platform was built up using Matlab and dSPACE. Finally, a control method for a bidirectional interlinking converter was developed to suppress the harmonics and improve the power quality of the system.
