1. CoEpower Active Harmonic Filter Overview

CoEpower Active Harmonic Filter is a new technique for power quality solutions that uses IGBT inverter-based 3-level topology technology to support fast real-time harmonic mitigation. The active powder filter offers a selectable priority function with reactive power compensation, load balancing, and harmonic filtering.

Active harmonic filter AHF is connected to the power system in parallel, and the power system data is collected in real-time through an external sampling Current Transformer CT. The internal DSP will react ultrafast with an intelligent FFT algorithm to calculate the required compensation current value and send a command to IGBT. The IGBT dynamically adjusts the switching frequency to optimize the performance and AHF to output a reverse ample but the same value current to offset harmonic current, thus reducing the harmonic distortion for each order, finally realizing a total harmonic distortion ratio below 5% according to IEEE 519 standard.
