Product Description
The working principle of the STD APF series active power filter is to detect the load current in real time, separate the harmonic currents one by one based on the specified harmonic current detection algorithm, and generate and control the driver IGBT output and load harmonic current according to the set filtering percentage. Compensation currents with the same amplitude and opposite phases achieve the purpose of harmonic cancellation.

PROTECT YOUR SYSTEM FROM RESONANCE.
* The current spectrum is analysed at 1024 individual points per cycle
* System impedance at each individual harmonic is effectively 'learnt' by the AHF
* Compensation current is slowly increased with system stability closely monitored
* Should resonance be detected at any point the intelligent FFT can skip the problematic point
BALANCE YOUR LOADS AND CORRECT YOUR POWER FACTOR TOO
* In addition to harmonic mitigation the AHF can provide load current balancing
* Reactive power can be compensated for thus increasing power factor
