APF active power filter cabinet
Short Description:
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.
