矩阵转换器 (MC) 负载的对称性破缺会产生不平衡，从而在 MC 输入侧引发准周期行为。此外，负载不平衡在输入侧产生负序电流。本文采用时滞反馈控制（TDFC）来衰减准周期振荡和对称性破缺引起的负序分量。结果表明，准周期行为的衰减直接导致负序电流分量的减少。结果，TDFC改善了MC在不平衡负载下的运行，并且在输入侧恢复了部分周期性对称性。
The symmetry breaking of the loads of a matrix converter (MC) generated an imbalance that induced a quasiperiodic behavior at the input side of the MC. In addition, the load imbalance generated a negative‐sequence current at the input side. This paper adopts the time‐delayed feedback control (TDFC) to attenuate the quasiperiodic oscillation and the negative‐sequence component caused by the symmetry breaking. The results indicate that the attenuation of the quasiperiodic behavior directly leads to a decrease of the negative‐sequence current component. As a result, the TDFC improves the operation of the MC under unbalanced loads and part of the periodic symmetry is regained at the input side.
