Abstract
A method and apparatus for converting direct current into alternating current. An initial voltage level of an input voltage source is changed using a dual converter to form a plurality of voltage sources. Each of the plurality of voltage sources has voltage levels different from the initial voltage level. An inverter is supplied direct current from the plurality of voltage sources formed by the dual converter. The direct current is converted into a number of alternating currents using the inverter.
