200/400V Active Harmonic Filter AHF ModuleOverview

Enjoypowers’ 200/400V active harmonic filter(active power filter) AHF module is a three-level inverter power management system used for power harmonics filtering, power factor correction, three-phase load balancing, effectively reducing line loss, and prolonging the service life of power equipment.

Enjoypowers’ 200/400V active harmonic filter AHF’s modular design allows flexibility in installation and integration. It is a preferred power quality solution for all power consumers, system integrators, and OEMs.

Operating principle

Enjoypowers’ AHF is connected in parallel with the nonlinear load and uses a set of current transformers (CT) to detect the load current. It calculates each order harmonic current through the FFT algorithm in its DSP chip, and then generates a compensation current with the same amplitude but opposite phase angle to the detected harmonic current, so as to offset the original load harmonic.

Features

High energy efficiency, due to three-level inverter technology
Integration of load balancing, power factor compensation, and harmonics filtering features into one module
Hybrid var compensation solution: built-in 16 DO ports to control ordinary capacitors, or RS485 interface to control intelligent capacitor
