Active Power Filter
Working principle
The active filter detects the load current in real time through the external current transformer CT, and
extracts the harmonic components of the load current through the internal DSP calculation. Then the PWM
signal is sent to the internal IGBT to control the inverter to generate a current equal to the load harmonic
and in the opposite direction into the power grid to compensate the harmonic current, to achieve the filtering
function.
