Selecting the best capacitor for your motor drive o t o r application M Aluminum capacitors are often used as DC link capacitors in motor drives, o r both in 1-phase and 3-phase designs. f The aluminum capacitor is used as an energy buffer to ensure stable operation of the switch mode inverter driving s the motor. The aluminum capacitor also functions as a flter to prevent high-ponents from the switch mode inverter from polluting the mains voltage. The key selection criterion for the aluminum capacit
