ABSTRACT:
A line harmonics reduction module is enclosed in a chassis having a receptacle and a plug on opposite faces, for connection externally to a computer system unit or similar electronic equipment between the AC line power cord and the AC power receptacle contained in the computer system unit. The module may contain passive components such as an inductor, or may contain active circuitry designed to reduce the amplitudes of current components at harmonics of the line frequency by forcing the current waveform to be more nearly sinusoidal.
