Three-phase unbalance refers to the inconsistency of the three-phase current (or voltage) amplitudes in the power system, and the amplitude difference exceeds the specified range.

Relying on the power electronics industry, Xichi Electric will not only serve the field of power transmission and distribution equipment, but also provide better product support for equipment manufacturing and new energy industries. To achieve the development goal of "where there is a motor, there is Xichi".

APF can not only compensate various harmonics, but also suppress flicker and compensate reactive power; the filtering characteristics are not affected by system impedance, etc., which can eliminate the risk of resonance with system impedance; it has an adaptive function, which can automatically track and compensate for changing Harmonics, that is, have the characteristics of high controllability and fast response.
