Abstract
A nested three-phase heater is disclosed herein. The nested three-phase heater includes a three-phase power supply, a set of three heating elements, and a controller. The set of three heating elements coupled to an aircraft part, each heating element of the set of three heating element coupled to a respective phase of the three-phase power supply. The controller is coupled to the three-phase power supply and the set of three heating elements. The controller is configured to control each of the phases of the three-phase power supply such that responsive to all heating elements of the set of three heating element being operational, the controller switches the phases to correspond to a respective predetermined time period in order that only two phases of the three-phase power supply are active and providing power during the predetermined time period.
