Abstract
A power conversion scheme employing a group of parallel connected, individually controlled converter circuits each providing output currents employs a scheme of distributed notches in the output currents to facilitate connection between common DC current and AC voltage sources. By the parallel connection of a pair of groups, time phase displaced group to group, additional power capability and harmonic reduction is achieved.
