摘要

以单相LC型离网逆变器为研究对象,针对传统微分器的不足,提出一种改进型数字微分器设计方法,改进型微分器与理想微分器的频率特性基本相同。最后,将改进型的微分器应用于电容电压有源阻尼控制策略中,硬件实验结果证实了所提方法的可行性。

Abstract

Addressing the shortcomings of the traditional derivatives, this paper proposes a design method of improved digital derivatives with the research object of single-phase LC off-grid inverter. The improved derivative proves to have the same frequency characteristics as the ideal derivative. Finally, the improved derivative is applied in the capacitor voltage active damping control strategy. Experimental results confirm the feasibility of the proposed method.
