The WBAPF three-level series active filter can directly or indirectly measure the current injected into the grid by a nonlinear load through a connected external current transformer. The detection and operation of harmonic and reactive compensation are performed in the digital control unit. The active filter generates a compensation current that cancels the harmonic components and the load reactive current, so that there is only a fundamental current in the grid. The active filter is able to adapt the changes in the magnitude of the load and system harmonic content in real time so that it can be treated at any time

An Actual Case of the AHF/APF:
Before the APF/AHF switch on: There are harmonic and reactive losses in the grid, resulting in power quality problems | After the APF/AHF switch on: generating reverse harmonic current and reactive current, dynamically compensating for harmonics and reactive power, guaranteed power quality |
