Beschreibung
Zusammenfassung:	An ice protection system and method capable of anti-icing and de-icing aerodynamic structures and surfaces is provided comprising a Resistive Heat Coat (RHC) controller and a heating device. The RHC controller comprises a RHC power circuit topology having a processor and a buck converter. The RHC controller further comprises a RHC control algorithm. The heating device comprises a plurality of resistive heating elements, such as CNT-based resistive heaters. The ice protection systems and methods disclosed can achieve an efficiency of 98% or greater while employing a direct current (DC) power supply and "hard switching" with a switching frequency of at least 500 kHz.
