Abstract
An exhaust aftertreatment system and a method thereof is provided. The system includes a heater configured to provide heat to a catalyst. The system further includes a heater control unit (HCU) configured to supply electrical power to the heater, and a power supply control unit (PSCU) configured to supply electrical power to the HCU at a variable voltage. The HCU is configured to determine a setpoint parameter which varies in response to variation in a commanded power output of the HCU to drive the heater. The PSCU is configured to receive the setpoint parameter and to adjust the variable voltage supplied to the HCU in response to the setpoint parameter. The adjustment of the setpoint parameter is effective to optimize an efficiency of the HCU during operation to supply the commanded power output to the heater.
