In this article, a computation-efficient model predictive control (MPC) is proposed to eliminate common-mode voltages (CMVs) of three-phase five-level active neutral-point-clamped (3P-5L-ANPC) converters. Originated from the CMV analysis of the 3P-5L-ANPC with all possible 125 possible voltage vectors, only 19 voltage vectors that generate zero CMV are adopted as the candidate voltage vectors for the MPC. The best voltage vector from the candidate voltage vectors is selected to track the current references. Then, appropriate switching combinations of the selected best voltage vector are determined to effectively balance the flying and dc-link capacitor voltages without any additional hardware components. Furthermore, the proposed MPC only chooses five candidate voltage vectors involving in MPC optimization according to the location of the reference voltage vector, which significantly alleviates the computational burden. Finally, the effectiveness of the proposed MPC in terms of the steady-state and dynamic performances is validated by simulated and experimental results.

具有共模电压消除的五电平 ANPC 转换器的高效计算模型预测控制

在本文中,提出了一种计算效率高的模型预测控制 (MPC),以消除三相五电平有源中性点钳位 (3P-5L-ANPC) 转换器的共模电压 (CMV)。源自对 3P-5L-ANPC 的 CMV 分析,所有可能的 125 个可能的电压向量,仅采用 19 个产生零 CMV 的电压向量作为 MPC 的候选电压向量。从候选电压向量中选择最佳电压向量来跟踪电流参考。然后,确定所选最佳电压矢量的适当开关组合,以有效地平衡飞跨电容器电压和直流链路电容器电压,而无需任何额外的硬件组件。此外,所提出的MPC仅根据参考电压向量的位置选择5个参与MPC优化的候选电压向量,显着减轻了计算负担。最后,模拟和实验结果验证了所提出的 MPC 在稳态和动态性能方面的有效性。
