Lvaf Active Power Filter

We are offering lvaf active power filter. Lvaf active power filter is a new power electronic device of dynamically suppressing harmonics, reactive power compensation, through real-time detection of the load current waveform and dsp calculation, to obtain content of load current harmonic, then a pwm signal to inverter controlled by igbt, such, to produce a current as big as load harmonic current but opposite direction into power supply system. Finally, the harmonic is filtered
