Abstract:
1. A two-source inverter system, the system comprising: a first voltage source; a second voltage source; a first switch set having first DC inputs, first AC outputs, and first control inputs, wherein the first DC inputs are coupled to the first voltage source, and wherein the first AC outputs are configured to be coupled to an AC multi-phase load; a second switch set having second DC inputs, second AC outputs, and second control inputs, wherein the second DC inputs are coupled to the second voltage source, and wherein the second AC outputs are configured to be coupled to the AC multi-phase load; and a controller coupled to the first control inputs and the second control inputs, the controller being configured to receive first feedback signals and second feedback signals from the first switch set and the second switch set respectively, and the controller being configured to control current flow through the first switch set and the second switch set; wherein the second switch set comprises:
