摘要

由于lc滤波器在开关谐波频率处具有良好的衰减能力，因此通常用作并网变换器的输出侧滤波器。lc -滤波器在变换器动力学中产生若干谐振，为了确保变换器的稳健性能，这些谐振必须加以抑制。利用有源阻尼(AD)代替无源阻尼，可以有效地衰减lc滤波器引入的谐振特性，从而提高转换效率。有源阻尼影响变换器的输出阻抗，为了分析电力电子系统基于阻抗的稳定性，需要对变换器的输出阻抗进行准确预测。本文提出了一种仅利用逆变侧电感电流反馈控制和主动阻尼的ICF变换器的小信号模型。此外，还对输出阻抗特性进行了全面分析。给出了3kw样机的实验测量值来验证分析。

Effect of single-current-feedback active damping on the output impedance of grid-connected inverter

LCL-filter is commonly used as an output-side filter in a grid-connected converter due to its good attenuation capability at the switching harmonic frequencies. LCL-filter creates several resonances in the converter dynamics which shall be damped for ensuring robust performance of the converter. The resonant behavior introduced by the LCL-filter can be attenuated with active damping (AD) instead of passive damping to improve the conversion efficiency. The active damping affects the output impedance of the converter, and the impedance should be accurately predicted in order to allow analyzing impedance-based stability of power electronics-based power systems. This paper presents the small-signal model for inverter-current-feedback (ICF) converter using only the inverter-side inductor current feedback for both control and active damping. Additionally, the output impedance properties are comprehensively analyzed. Experimental measurements from 3-kW prototype are presented to verify the analysis.
