1.Product Description
CoEpower APF series Dynamic harmonic compensation filter AHF（APF for short is a new type power electronic product with functions of dynamic harmonic compensation (varying amplitude and frequency) 、reactive power compensation (leading or lagging and three phase unbalance correction.Dynamic harmonic compensation filter AHF is a controllable current device preventing resonance on mechanism, not generating nor amplifying harmonics.
Dynamic harmonic compensation filter AHF can be used to filter out harmonics in the power system which are significantly below the switching frequency of the filter.The main difference between Dynamic harmonic compensation filter AHF and passive power filters is that AHF mitigates harmonics by injecting active power with the same frequency but with reverse phase to cancel that harmonic, where passive power filters use combinations of resistors (R), inductors (L) and capacitors (C) and does not require an external power source or active components such as transistors. This difference, make it possible for AHF to mitigate a wide range of harmonics.

5.Working Principle
Dynamic harmonic compensation filter AHF is a direct current-space-vector control active power filter (APF) based on a three-level neutral-point-clamped (NPC) voltage-source inverter.AHF is connected in parallel with non-linear loads, and uses external current transformers (CT) to detect the load current. It calculates each order harmonic current , and then generates a compensating current with the same amplitude but opposite phase angles to offset the harmonics.
