Abstract
In some embodiments, the instant invention provides a drive filter that includes: a plurality of input contacts configured for receiving an initial three-phase alternative current from a three-phase alternative current power source; a plurality of output contacts configured for outputting an output current to a respective phase of an adjustable speed drive, where the adjustable speed drive has a direct current bus capacitance between 1 and 30 microfarads (uF); and a plurality of electrical connections, where each electrical connection is configured to connect each input contact of the plurality of input contacts to a respective output contact of the plurality of output contacts; and where each electrical connection consists of at least one line capacitor; and where the at least one capacitor has a capacitance value such that a total harmonic current distortion (THID) of the output current is reduced to 5 percent or less.
