A method includes selecting a state model control, as an operational state of the heater, from among a plurality of state model controls, measuring an electrical characteristic of the heater, where the electrical characteristic includes at least one of an electric current and a voltage, and controlling power to the heater based on the selected operational state and based on the measured electrical characteristic.

System and method for controlling power to a heater

A control system includes a power converter being a step-down voltage converter and including a power switch. The power converter is operable to generate an adjustable output voltage and includes a sensor circuit configured to measure at least one of a voltage and an electric current of the heater. The control system includes a controller connected to the power converter and the sensor circuit. The controller is configured to determine an input parameter based on the at least one of the voltage and the electric current. The input parameter is indicative of a temperature of the heater. The controller is configured to set the output voltage applied for the heater based on the input parameter and a desired setpoint. The desired setpoint is based on an operational state of the heater. The controller is configured to operate the power switch of the power converter to generate the output voltage.
