Abstract
The vehicle generator includes a rotor wound with a field winding, a stator wound with a stator winding, rectifier modules respectively connected to corresponding output terminals of the stator winding, and a power generation control device to control a power generation voltage of the vehicle generator formed from outputs of the rectifier modules by controlling an excitation current flowing through the field winding. Each of the rectifier modules includes a pair of a first MOS transistor and a second MOS transistor series-connected between positive and negative terminals of a battery. The rectifier modules are connected with one another through a communication line. The rectifier modules exchange data regarding control of the first and second MOS transistors of the rectifier modules by a pulse train signal transmitted on the communication line.
