Energy management in an airflow regulator

Artificial respirators use an electric source of energy to supply the various active components which control the airflow. A portable or autonomous respirator (emergency, war, ambulance, etc), needs a battery or an energy container to be supplied with great reliability. This paper describes an industrial project that uses only pneumatic energy to supply all the electronic components. Furthermore, the generator used for the electric supply regulates the airflow by controlling its phase currents
