APF 工作原理 Working principle
有源電力濾波器通過外部電流互感器 CT，實時檢測負(fù)載電流，并通過內(nèi)部 DSP 計算，提取出負(fù)載電流的諧波成分，然后通過 PWM 信號發(fā)送給內(nèi)部 IGBT，控制逆變器產(chǎn)生一個和負(fù)載諧波大小相等、方向相反的電流注入到電網(wǎng)中補(bǔ)償諧波電流，實現(xiàn)濾波功能。
The active power filter detects the load current in real time through the external current transformer CT, and extracts harmonic components of the load current through internal DSP calculation, and then sends the harmonic components to the internal IGBT through PWM signals to control the inverter to generate a current with the same magnitude and opposite direction as the load harmonic and inject the current into the power grid to compensate the harmonic current, thus realizing the filtering function.
