Beschreibung
Zusammenfassung:	Systems include a prime mover that generates power for a mobile vehicle; a power converter that receives a portion of the generated power, and provides configured electrical power to an aftertreatment heater device configured to selectively heat an exhaust fluid of the prime mover; at least one aftertreatment component positioned downstream of the aftertreatment heater device, and configured to treat a constituent of the exhaust fluid; and a controller including an operating conditions circuit structured to interpret an operating parameter of one of the power converter, the aftertreatment heater device, the prime mover, or the exhaust fluid; a heater management circuit that determines a heating power value in response to the operating parameter; and a heater control circuit that provides a heating command in response to the heating power value; and wherein the power converter is responsive to the heating command to heat the exhaust fluid of the prime mover.
