ABSTRACT:
An ultor voltage generator for a television receiver includes a piezoelectric transformer arrangement constituting a plurality of piezoelectric transformer elements, each having input, output and common electrodes. The voltage gain characteristic of each element has a relatively narrow frequency bandwidth about its natural frequency of mechanical vibration. The plurality of piezoelectric transformer elements are electrically connected in parallel. The output electrodes are connected to a supply terminal of the arrangement, and the input electrodes and common electrodes are connected to input and common terminals, respectively, of the arrangement. A source of alternating voltage is coupled between the input and common terminals to generate a higher amplitude alternating output voltage between the supply and common terminals. The alternating output voltage is applied to a doubler rectifier to generate a DC ultor voltage for the television receiver picture tube. The natural frequencies of the plurality of piezoelectric transformer elements differ from one another substantially in order to produce a resultant voltage gain characteristic of the entire arrangement that is of significantly broader frequency bandwidth than that of any one of the constituent elements.
