Low voltage Active power flter APF/SVG

The active power filter cabinet and static reactive power generation cabinet detect the load current in real time through an external current transformer CT, and extract the component/reactive power of the load current through internal DSP measurement. Then, the internal IGBT is sent through a PMW signal to control the inverter to generate a current equal in magnitude and opposite in direction to the load harmonic/reactive power, which is injected into the power grid to compensate for the harmonic current/reactive power and achieve filtering/compensation functions.
