Active Power Filter (APF) Power Quality Solution at 400V, 480V, 690V, 1140V
有源电源滤波器（APF）电源质量解决方案，400V，480V，690V，1140V
- HKK-APF工作原理：
- 有源电源滤波器通过外部电流互感器CT及时检测负载电流，并通过内部DSP计算提取负载电流的谐波分量，并通过PWM信号发送到内部IGBT
- 具有与负载谐波相等大小但具有由控制逆变器产生的相反方向的电流被注入到电网的补偿谐波电流，以合理地控制谐波

- HKK-APF operating principle:
- The active power filter detects the load current timely through the external current transformer CT and extract the harmonic component of the load current through internal DSP calculation and sends it to internal IGBT through PWM signal
- The current with the equal size of the load harmonic wave but with the reverse direction as generated by the control inverter is injected to the compensation harmonic wave current of the power grid to govern the harmonic wave reasonably
