What is a power line filter?
Power line filter is electrical equipment which effectively filters particular frequency point in the power line or the frequency out of the particular frequency point. Power line filter performance is to get a certain frequency power supply signal or power supply signal after eliminating a certain frequency through connecting power supply filter in power line. Based on this performance of power line filter, a square wave group or compound noise wave could be converted into a certain frequency sine wave through power line filter.
Power supply filter is a passive bi-directional network, that is, one end is power supply, and the other end is load. Power supply filter principle is a impedance adaption network: the larger the impedance mismatching is (between “power filter input&output” and “power & load” side), the more effective the attenuation of electrical magneto interference is.
