Abstract
The invention concerns a voltage converter of the flyback converter type, having a switching element on the primary side in relation to an inductor and an output capacitor on the secondary side which can be charged as a reaction to a current which flows in the inductor and which is switched by the switching element, said output capacitor being associated with a blocking element on the secondary side, wherein the blocking element is in the form of a further switching element which can be put into a blocking condition by a control signal, and there are provided control means for production on the primary side of the control signal, which are such that the control signal is produced a predetermined time interval before a conducting condition of the switching element on the primary side.
