中文摘要:
      针对级联H桥整流器自身非线性特性,通过分析单相两级级联H桥整流器拓扑结构,提出了基于级联H桥交流侧合成电压解耦控制的二维调制平衡控制策略。采用新的解耦控制方法和二维调制算法,提高了系统直流侧电压的响应速度和系统的抗干扰能力。搭建了基于MATLAB/Simulink的仿真模型和基于RT-lab的半实物实时仿真实验平台,仿真和实验验证了所提出的控制策略的有效性与可行性。
英文摘要:
      In consideration of the nonlinear characteristics of a cascaded H-bridge rectifier and through the analysis of the topology of a single-phase two-level cascaded H-bridge rectifier, a two-dimensional modulation control strategy is proposed based on the decoupling control of AC-side synthesized voltage of cascaded H-bridge. Using the novel decoupling control method and the two-dimensional modulation algorithm, the response speed of DC-side voltage and the system's anti-disturbance capability are improved. A simulation model based on MATLAB/Simulink and a hardware-in-the-loop real-time simulation experiment platform based on RT-lab were built up, and simulation and experimental results verified the validity and effectiveness of the proposed control strategy.
