Abstract :
This paper presents practical design guidelines for designing LC filters for AC-motor drive applications. A DC choke and an electrolytic capacitor bank on the DC bus filter the voltage and the current ripples and improve the input power factor. Capacitor and choke values are derived to optimize overall filter performance. Costs associated with the respective component values can then be obtained to analyze cost trade-offs between selected values. Helpful hints are also given
