有源滤波器APF工作原理Working principle of active filter APF
The IVD active filter APF detects the load current through the external sampling current transformer CT, and performs FFT calculation through the internal DSP to separate the fundamental current and harmonic current, extract the harmonic current number and size, and then pass the PWM The signal is sent to the IGBT, and the inverter is controlled to generate a current equal to the load harmonic and in the opposite direction to be injected into the power grid to compensate the harmonic current to cancel, realizing a perfect filtering function.
IVD有源滤波器APF通过外部采样电流互感器CT，实施检测负载电流，并通过内部DSP进行FFT计算，将基波电流和谐波电流进行分离，提取出谐波电流次数和大小，然后通过PWM信号发送给IGBT，控制逆变器产生一个和负载谐波大小相等、方向相反的电流注入到电网中进行补偿谐波电流进行抵消，实现完美的滤波功能。
