Abstract
In a voltage converter including a half bridge in the form of controlled semiconductor switches, a transformer and a rectifier circuit, in which a primary winding of the transformer connected in series with at least one capacitor is connected to the half bridge, the at least one capacitor is arranged such that the resonant frequency of the series combination of the at least one capacitor and an inductance which inductance is active when the rectifier circuit is in operation, is larger than half the pulse frequency with which the semiconductor switches are controlled. Similar measures can also be carried out with a voltage converter with a direct coupling, in which a longitudinal coil and a transverse coil then substitute for the transformer.
