Filters provide harmonic performance guarantees while others may require extensive analysis This paper demonstrates that theoretical performance is not necessarily a valid estimate of the actual expected performance of most mitigation techniques when operating under real life conditions The performance level of most techniques diminishes in the real world due to the presence of unbalanced line voltages and operation at less than 10090 loading conditions VI TE APPLICATION NOTE CORPORATIOM July 2002 Doc AN0105 Solving DC Drive Harmonics with Matrix Harmonic Filters Matrix Filters may be used for phase controlled DC drive applications to improve power factor and reduce line harmonics Application to DC drives is similar to AC drives with a few important differences in filter performance and the selection of the appropriate filter rating The following paragraphs cover these differences Matrix Filter Selection Selection of the proper Matrix Filter rating for a DC drive 1s based on the horsepower and voltage rating of the drive Applications for DC motors rated at 500 volts or higher may use a 480 VAC filter rated at the same horsepower as the DC drive provided the motor efficiency 1s a minimum of 85 DC motors with lower efficiencies will typically draw higher ac input current and therefore a Matrix Filter rated for higher horsepower may be required The following equation should be used to select the correct filter ratin
