The power noise filter(PNF) is a new type of device which can effectively reduce the alternatingelectric wirenoise andimprove the electric device's capacity of resisting disturbance and the reliability of system. Ithas two functions. On one hand, it can remove or reduce the noise disturbancefrom the alternating current electric wire which will make the electric device work normally. On the other hand, it can prevent the noise generated by the electric device from entering into the electric wire. Many factors can generate high frequency noise disturbance signal on the alternating current electric wire, and the high frequency disturbance signal will enter into the electric device through the power, so it will reduce the noise-signal ratio greatly and there will be nonlinear distortion.
