ABSTRACT:
A transformer arrangement with a piezoelectric transformer and a carrier will be disclosed. The transformer has a body in the form of a board. The transformer operates with thickness mode vibrations. The body is rigidly connected to the carrier in at least one peripheral region in which anti-nodes of a horizontal oscillation of the body appear.
