Pulse width modulated multiple heater control

A system includes, in one example, a first heater device, a second heater device, and a temperature sensor, each disposed within a fluid flow. The system further includes a controller communicatively coupled to the first heater device, the second heater device, and the temperature sensor. The contro...

Beschreibung
Zusammenfassung:	A system includes, in one example, a first heater device, a second heater device, and a temperature sensor, each disposed within a fluid flow. The system further includes a controller communicatively coupled to the first heater device, the second heater device, and the temperature sensor. The controller is configured to receive, from the temperature sensor, an indication of a measured temperature of the fluid flow. The controller is further configured to control, based on a difference between the measured temperature of the fluid flow and a target temperature, operation of the first heater device via a first pulse width modulation signal and operation of the second heater device via a second pulse width modulation signal.
