一、产品概述
有源电力滤波器主电路为IGBT功率变换器,采用基于瞬间无功功率理论的检测技术,自动跟踪电网谐波变化,具有高度可控性与快速响应性。克服了传统无源滤波器的滤波效果差、容易发生谐振、只能滤除固定谐波的缺点,对各种快速瞬变的冲击性负荷均能起到良好的滤波和补偿效果。
DY-APF系列第二代有源滤波器是一体式有源滤波器的技术升级产品。DY-APF系列有源滤波器采用军工级控制芯片,计算能力及抗干扰性极强,可实现一个控制器集中控制多台有源滤波器并联工作,采用自适应电流平均值控制算法并结合LCL拓扑结构,克服了传统的滞环电流控制由于开关频率变化所带来的输出频谱范围宽、滤波较困难、高频谐波会干扰电网等缺点。
