LCL滤波器在现代的可再生能源行业的应用十分的普遍，可以有效、经济地确保和提高从能源到电网的馈电质量。滤波器用于过滤逆变器工作产生的开关频率。在达到目标畸变水平的同时，滤波器还会节约比较可观的成本。LCL滤波器的典型特点是损失小、体积小、重量轻、电容大。-LCL filter in the application of modern renewable energy industry is very common, can be effectively and economically to ensure and improve the quality of energy to the grid feed. This filter is used to filter the inverter switching frequency. The filter will reach the target distortion level at the same time, considerable cost savings. LCL filter typically characterized by loss, small size, light weight, large capacitance.
