Abstract
A method and apparatus for converting direct current into alternating current. The direct current is converted into a number of alternating currents using a switch system. The number of alternating currents is filtered using a set of inductors and a set of capacitors. Higher-frequency electromagnetic interference is blocked using a choke located between the set of inductors and the set of capacitors.
