Abstract

Die Erfindung bezieht sich auf einen serienabgestimmten piezoelektrischen Wandler. Erfindungsgemäß weist dieser Wandler primär- und sekundärseitig jeweils eine Impedanztransformations-Einrichtung auf, wobei die primärseitige zwischen einer Serieninduktivität (L1) und den primärseitigen Metallisierungsflächen (2, 4) der Keramik (6) und die sekundärseitige zwischen den Metallisierungsflächen (10, 12) und einer Gleichrichterschaltung (8) angeordnet sind. Somit erhält man einen Wandler, mit dem Leistung in Höhe von einigen Watt zu elektrischen Baugruppen auf hohem und sich schnell ändernden elektrischen Potential übertragen werden kann.
