研究目的
To optimally design the passive damping circuit for the LCL ?lters and LCL with multituned LC traps to address harmonic stability problems caused by the resonance of high-order ?lters in power electronic systems.
研究成果
The proposed method simplifies the iterative design of the overall ?lter while ensuring the minimum resonance peak with a lower damping capacitor and a lower rated resistor. It is shown that there is only one optimal value of the damping resistor or quality factor to achieve a minimum ?lter resonance. The passive ?lters are designed, built, and validated both analytically and experimentally for veri?cation.
研究不足
The use of passive damping provides a robust solution to harmonic stability problems but at the price of reduced ef?ciency due to the presence of additional passive components.
