摘要

随着电力电子技术的出现，由电力系统提供的非线性负载越来越多，这固有地带来了有关电能质量的各种问题。谐波就是这样一个问题，它的缓解必须以最大的关注来研究。为此，无源滤波器是一个简单，强大和经济有效的选择。本文提出了一种无源谐波滤波器的设计，以减轻双变流器供电的单相交光伏混合系统的源侧谐波。对带滤波器和不带滤波器的结果进行了分析，发现在安装滤波器后，电流谐波有所减少，这可以从源电流波形的THD降低中看出。

Application of passive filters for harmonics mitigation in a dual input converter

With the advent of power electronics there is an increased number of non-linear loads fed by an electrical system which inherently brings in various issues regarding power quality. Harmonics is such an issue and its mitigation must be looked into with utmost concern. For this, passive filters are a simple, robust and cost effective choice. The paper presents the design of passive harmonic filters to mitigate the source side harmonics of a single phase AC - PV hybrid system which feeds a dual converter. The results obtained with and without filters are analyzed and it is found that after the installation of filters there is a reduction in current harmonics which is evident by the reduction in THD of the source current waveform.
