Three-phase harmonic filter reactor

Enjoypowers’ 200/400V Active Harmonic Filter(active power filter) AHF Module is a flexible and modular power quality product for harmonic mitigation, power factor correction and three-phase balance. 1. 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. 2. 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. 4. 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 Precise compensation, high-speed response, Overall response time <7.8ms Load balancing and unloading of neutral wires.
