Title:
OUTPUT STAGE FOR ADAPTING AN AC VOLTAGE SIGNAL OF AN ULTRASOUND GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/012834
Kind Code:
A3
Abstract:
The present invention relates to an output stage for adapting an AC voltage signal of an ultrasound generator to a converter connectable to the output stage, wherein the output stage has two input terminals for receiving the AC voltage generated by the ultrasound generator and two output terminals for outputting an adapted AC voltage signal, as well as an output transformer with a primary coil having a number of turns n1 and a secondary coil having a number of turns n2. The output transformer has a main inductance LH and a leakage inductance Lσ, the two input terminals being connected via the primary coil and the two output terminals via the secondary coil. In order to specify an output transformer that allows an economical and compact adaptation of a generator output to the converter input, according to the invention a filter capacitor Cp is provided, which either connects the two output terminals in parallel to the secondary coil or connects an output terminal to a tap of the secondary coil or is connected to a filter inductor with n3 turns, which is inductively coupled to the primary and the secondary coil.
