Product Description

Active Power Filter KCAPF

  A P F is based on the theory of instantaneous reactive power in three-phase circuits. According to the different compensation objects, it is usually divided into two types: parallel type and series type. The parallel type is mainly used to control the harmonics caused by the current; the series type is mainly used to control the harmonics caused by the voltage. The practical application is mainly parallel type.
     The basic working principle of  A P F is: the active power filter detects the load current through the current transformer, and through the internal D S P calculation, extracts the harmonic components in the load current, and then sends it to the internal I G B T through the P W M signal to control the inverter to generate A harmonic current equal to the load harmonic current and opposite in direction is injected into the power grid to achieve the purpose of filtering
