Abstract
Various embodiments may relate to a synchronous rectifier including at least one rectifier cell, to which power is supplied via a secondary winding of a transformer arranged between the input connections of the synchronous rectifier. The rectifier cell comprises a bipolar main switch operated in the inverse mode, wherein an energy store is provided in the base line of the bipolar main switch, which energy store, in conjunction with an auxiliary switch which is concomitantly controlled by the relevant secondary winding for the bipolar main switch, ensures that the main switch is switched off prior to the end of the inverse phase.
