Abstract
A circuit assembly is used for controlling a piezoelectric transformer having an input capacitance in a first circuit branch. The circuit assembly also includes a second circuit branch for compensating for the input capacitance, preferably by means of a capacitive element, and a differential amplifier having two inputs. The first input is coupled to the first circuit branch and the second input is coupled to the second circuit branch.
