Product Advantages
The FGAPF active power filter is a new generation of harmonic management solution that dynamically filters harmonics and uses advanced dynamic real-time tracking compensation to eliminate harmonics from power grid. The APF is a high-power electronic device based on current detection and current injection technology. By monitoring the current waveform generated by nonlinear loads in real time, it separates the harmonic part and injects harmonic currents of opposite size and direction into the grid by controlling the triggering of the IGBT to achieve the function of filtering (offsetting) harmonics, thus improving the safety and reliability of the electrical system and achieving energy saving and efficiency.
