Title: Switching strategy for increased efficiency of power converters

Abstract

Systems and methods for operating a power converter are provided. A DC to AC converter can include an inner converter and an outer converter. The inner converter can include an isolation transformer a first plurality of switching devices. The outer converter can include a second plurality of switching devices. A control method can include determining an output voltage of the outer converter. The control method can further include controlling operation of the inner converter based at least in part on the output voltage of the outer converter.
