| 摘 要： | 本文以三线四线制三电平三桥臂电容中分型APF的谐波补偿作为研究内容,分析了控制量一拍滞后实施对传统无差拍控制的影响,提出了一种改进型无差拍控制,在系统模型参数精确的情况下,将完全消除电压控制量一拍滞后实施的影响。实验结果表明改进无差拍控制器较好地计算出合适的电压控制量,证明改进无差拍的正确性和可行性。

| Abstract: | Focused on harmonic suppression technology of 3-phase 4-wire tri-level three-leg neutral-point split APF, the traditional deadbeat control affected by one-beat-delay implementation is analyzed in detail and a improved deadbeat control is proposed. With precise model parameters, the improved deadbeat control completely eliminate the affect of voltage references by one-beat-delay implementation. The results show that the deadbeat controller is enabled to calculate the appropriate amount of voltage control, and verifies that the improved deadbeat is correct and feasible. |
