Abstract: Power conversion systems, filter circuits and integrated filter resistor and inductor apparatus are presented, in which a damping resistor is integrated with a filter inductor by winding joined resistor winding portions proximate to one another at least partially around a filter inductor core leg to form an integrated filter resistor and inductor apparatus for interconnection with filter capacitors to provide an input filter or an output filter for a motor drive or other power conversion system.
