A circuit is provided for an alternator of a motor vehicle with the winding of the alternator consisting of two half-windings, with rectification of the voltages and currents at the outputs of the two half-windings taking place, with the outputs of one half-winding being connected with the inputs of a first rectifier, and with the outputs of the other half-winding being connected with the inputs of another rectifier, and with each output of one half-winding being connectable across the gaps of two switchable elements with two outputs of the other half-winding in each case such that when the gaps are bridged, the two half-windings are connected electrically in series. In a method for triggering the switchable elements, the individual thyristors are triggered in succession and/or only individual transistors are triggered, with this preferably taking place when a certain motor rpm is undershot. Diodes c an also be used instead of individual thyristors.
