Abstract

Foil-based PTC heaters are self-regulating, i.e. do not need any electronic control unit (ECU) to limit the maximum heating current. In order to establish different heating power levels the present invention proposes to choose different PTC ratio/onset characteristics. In addition, the print design of the PTC ink can be adjusted accordingly.
