I-APF active filter

Product Introduction

The I-APF series parallel active power filter device integrates dynamic filtering and dynamic compensation, which can be flexibly set and has superior performance. It has the characteristics of fast response speed, high filtering efficiency, easy installation and operation, simple maintenance, and filtering performance not affected by system parameters. It is one of the most ideal filtering compensation products. The device adopts high-performance control chips and fully controlled power electronic devices, using the most advanced control theory and fully digital control methods to detect the load current in the power grid in real time, quickly separate the harmonic current components, and generate control instructions based on the magnitude of the harmonic current. It injects compensation currents of equal magnitude and opposite direction into the power grid in real time to achieve instantaneous filtering of harmonics; At the same time, it can also provide leading or lagging reactive current to improve the power factor of the power grid and achieve dynamic reactive power compensation.
