add to cart
- 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
