[0002] A power filter is an electrical device that can effectively filter out frequencies at or outside a specific frequency in a power line. The function of a power filter is to obtain a power signal at a specific frequency or to eliminate a power signal after a specific frequency is eliminated by connecting the power filter to the power line; a power filter is usually installed at the power input end of an electrical device. The purpose of this is to filter out possible power noise and interference before the power enters the device.
