Induction heating coils with uniform heating
An induction heating system employs a ferromagnetic susceptor mounted proximate an exterior of flight surface of an aircraft. At least one electrically conductive coil is mounted proximate the ferromagnetic susceptor. The at least one electrically conductive coil is powered by a first power source with a first frequency. At least one compensating coil is mounted proximate the ferromagnetic susceptor having a geometry determined to provide substantially net-zero flux with respect to the at least one electrically conductive coil and positioned to induce induction heating where the first plurality of electrically conductive coils lacks induced inductive heating coverage. The at least one compensating coils is powered by a second AC power source with a second frequency.
