基于负序电容的多重低次谐波电流抑制方法

In a microgrid system, the dc bus contains a significant amount of undesired low-order harmonic currents (LHC) when multiple converters of various types and with nonlinear behavior are connected. To address the issue, this article proposes an iterative control strategy based on a negative-order capacitor (NOC) branch on dc bus. In the proposed method, the reference voltage of decoupling capacitors...
