Abstract

In accordance with an embodiment, a method in a voltage converter includes, in each of successive drive cycles, switching on for an on-period a first electronic switch connected in series with a primary winding of a transformer. Before first electronic switch is switched on, the transformer is pre-magnetized for a pre-magnetizing period, where there is a first delay time between an end of the pre-magnetizing period and a beginning of the on-period.
