An apparatus for selectively rectifying one of a pair of output voltages associated with one of a a pair of output winding sets of a polyphase alternating current generator has a single controlled bridge rectifier selectively coupled to one of the winding sets. The bridge rectifier is selectively coupled in accordance with a predetermined rotational speed of the rotor. Transitions between the two winding sets is caused to occur at zero current conditions of the windings.
