Pulse Width Modulation (PWM) Furnace

Home : Products : MapleSim : Model Gallery : Pulse Width Modulation (PWM) Furnace

Some industrial ovens require careful control of the temperature. A thermostat controller relies on variations in temperature, which would not be desirable. A Pulse Width Modulation (PWM) controller pulses the heater on and off with varying durations, depending on the output of a PID controller. This way, the temperature can be accurately controlled.
