Abstract: Presented herein are systems and methods of selectively activating legs of converters. The system can include a power converter comprising a plurality of legs to convert electrical power conveyed between a source and a load. The system can include a controller structured to be coupled with the power converter. The controller can identify a parameter defining an operating condition of the power converter. The controller can determine a number of legs of the power converter to use based on the parameter. The controller can identify a metric indicating a utilization of each leg of the plurality of legs. The controller can cause activation of at least a subset of legs of the plurality of legs in accordance with the number of legs and the metric, to convey the electrical power between the source and the load.
