Vehicle generator

A vehicle generator comprising:

• a rotor wound with a field winding for energizing magnetic poles of the rotor;
• a stator wound with a stator winding as a multi-phase winding for generating an AC voltage depending on a rotating magnetic file generated by the field 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;
• wherein 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, and
• 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.
