This article presents a simplified model predictive control (MPC) method for single-phase four-level hybrid-clamped converters (1P-4L-HCCs), achieving high-quality current control and strong capacitor voltage balancing. Different from a conventional MPC, the proposed method aims to dramatically reduce switching states (control voltage vectors) in the cost function optimization of MPC. It utilizes only 16 switching states, compared to 64 in conventional methods, resulting in reduced execution time and significantly increased control bandwidth. Steady-state and dynamic performances are evaluated by simulated and experimental test, and the main results are provided to verify the effectiveness of the proposed MPC method.

单相四电平混合钳位转换器的低复杂度模型预测电流控制

本文提出了一种用于单相四电平混合钳位转换器 (1P-4L-HCC) 的简化模型预测控制 (MPC) 方法，实现了高质量的电流控制和强大的电容器电压平衡。与传统的 MPC 不同，所提出的方法旨在显着减少 MPC 成本函数优化中的开关状态（控制电压矢量）。与传统方法中的 64 个开关状态相比，它仅使用 16 个开关状态，从而减少了执行时间并显着增加了控制带宽。通过仿真和实验测试对稳态和动态性能进行了评估，并提供了主要结果以验证所提出的 MPC 方法的有效性。
