Abstract
A method and system for increasing the output of an alternator for an automotive vehicle has a first three-phase winding (18) and a second three-phase winding (20) that are coupled to a respective first rectifier circuit (26) and a second rectifier circuit (28). A switch circuit (30) is located between the first rectifier circuit (26) and the second rectifier circuit (28). A controller (32) that is coupled to a speed sensor (34) and provides a signal indicative of the speed of the alternator, controls the operation of the switch circuit (30). When the speed sensor (34) indicates that the speed of the alternator is below a predetermined threshold, the first rectifier circuit (26) and second rectifier circuit (28) are coupled together through switch circuit (30). When the speed sensor (34) indicates that the speed of the alternator is above a predetermined speed, the switch circuit (32) is controlled to an open state so that two parallel half-wave rectifier circuits are formed.
