Abstract
A flow generator configured to supply the flow of breathable gas and a humidifier configured to humidify the flow of breathable gas. The humidifier has a water reservoir and a heater configured to heat water in the water reservoir. The respiratory apparatus further includes an air delivery tube with a heating element and a controller in communication with both the flow generator and the humidifier. The air delivery tube is configured to receive the humidified flow of breathable gas from the humidifier. The controller is configured to coordinate a humidifier heater duty ratio with an air delivery tube heating element duty ratio so that the humidifier and the air delivery tube heating element do not draw power simultaneously. The controller also applies a 100% maximum duty ratio when below a given heater element threshold and a fixed duty ratio when above the threshold, the fixed duty ratio being determined based on a target evaporation rate.
