有源濾波器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有源濾波器APF通過外部采樣電流互感器CT，實施檢測負載電流，并通過內部DSP進行FFT計算，將基波電流和諧波電流進行分離，提取出諧波電流次數和大小，然后通過PWM信號發送給IGBT，控制逆變器產生一個和負載諧波大小相等、方向相反的電流注入到電網中進行補償諧波電流進行抵消，實現完美的濾波功能。
