The active filter detects the load current in real time through the external current transformer CT, and calculates it through the internal DSP to extract the harmonic components of the load current, and then sends it to the internal IGBT through the PWM signal to control the inverter to generate a harmonic with the load.
APF principle
The active filter detects the load current in real time through the external current transformer CT, and calculates it through the internal DSP to extract the harmonic components of the load current, and then sends it to the internal IGBT through the PWM signal to control the inverter to generate a harmonic with the load. Currents of equal size and opposite direction are injected into the power grid to compensate for harmonic currents and achieve filtering functions.
