有源电力滤波器
●工作原理
■有源电力滤波器通过外部电流互感器CT,实时检测负载电流,并通过内部DSP计算,提取出负载电流的谐波成分,然后通过PW.M信号发送给内部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补偿谐波电流,实现滤波功能。
●How it works
■The active power filter (APF) detects the load current in real-time through the external current transformer <CT), and extracts the harmonic component of the load current through the internal DSP calculation. The M signal is sent to the internal IGBT to control the INVERTER, and a current equal to and opposite to the load harmonic is injected into the power network to compensate the harmonic current and realize the filter function.
