    Abstract: A method is provided for reducing emissions from a hybrid vehicle having an exhaust aftertreatment system. The method includes: receiving, by a controller, emissions data regarding an emissions level of a hybrid vehicle having an exhaust aftertreatment system from a sensor; determining, by the controller, that the emissions level is at or above a predefined threshold; adjusting, by the controller, an operating point of an engine of the hybrid vehicle based on the emissions level being at or above the predefined threshold; and controlling, by the controller, an elector motor in response to the adjustment of the operating point of the engine to compensate for a change in power output from the engine and to reduce the emissions level to below the predefined threshold.

    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.
