One exemplary embodiment is a vehicle system comprising an engine, an exhaust aftertreatment system including a heating element, an electric machine configured to selectably operate as a motor or a generator, an inverter module including a plurality of inverter phase legs and an auxiliary leg, and an electronic control system in operative communication with the inverter module and the exhaust aftertreatment system. The electronic control system is configured to evaluate whether the electric machine is operating as a generator, selectably operate the plurality of inverter phase legs to rectify AC power received from the electric machine, evaluate whether to heat one or more components of the exhaust aftertreatment system, and selectably operate the auxiliary leg to provide rectified power from the inverter legs to one or more electrical heating elements thermally coupled with the one or more components exhaust aftertreatment system effective to heat the one or more components.
