Abstract

For the interleaved parallel structure of resonant modular multilevel DC-DC converter （MMDC）, a continuous control set model predictive control （CCS-MPC） is proposed for the current inner loop control. The working mode of the converter in boost mode is analyzed, and the inductance current prediction model in boost mode is established. Compared with the traditional PI control, it avoids the tedious parameter adjustment and improves the dynamic performance of the system. Finally, the simulation and experimental results of the two kinds of control are analyzed and compared through the simulation and physical experiment platform, which proves the feasibility and effectiveness of the proposed method.
