Abstract

Die Erfindung betrifft einen kontaktlosen Datenträger (2) mit einem Koppelelement (L1), einer ersten und einer zweiten Gleichrichterschaltung und einem Umschalter (S1), der mit einer Modulatorsteuerschaltung verbunden ist, zur Umschaltung zwischen den beiden Gleichrichterschaltungen, so dass eine Gleichspannung UV durch die eine und/oder die andere Gleichrichterschaltung erzeugt wird. Ausserdem weist der Datenträger (2) eine Spannungsregelschaltung (DZ)auf, die mit den Ausgängen beider Gleichrichterschaltungen verbunden ist. Die beiden Gleichrichterschaltungen stellen unterschiedliche Belastungen dar, so dass durch das Umschalten von einer Gleichrichterschaltung auf die andere eine Lastmodulation realisiert ist.
