摘要

针对谐振型模块化多电平直流变换器（MMDC）交错并联结构,在电流内环控制上提出基于连续控制集模型预测控制（CCS-MPC）。分析变换器在升压模式下的工作模态,建立升压模式下的电感电流预测模型。相较于传统PI控制,避免繁琐的参数调整,提高系统动态性能。最后,通过仿真与实物实验平台进行验证,分析比较两种控制的仿真和实验效果,证明所提方法的可行性和有效性。

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.
