Abstract
A system for receiving DC input and for providing AC output is disclosed having first and second inverters. The first inverter has an input for receiving DC input and an output for providing a first inverter output and the second inverter has an input for receiving DC input and an output for providing a second inverter output. An inverter controller is connected to the first and second inverters for controlling the first and second inverters such that the first and second inverter outputs are separated in phase by a predetermined number of degrees in order to suppress harmonics in the AC output. An output circuit is arranged to combine the first inverter output and the second inverter output into the AC output.
