ABSTRACT:
A control voltage setting circuit 31 provides one of a pair of control voltages when one of a pair of command signals are transmitted from an upper control unit 4 which is disposed outside the alternator. The command signals correspond respectively to upper and lower desired output voltages of the alternator. A voltage regulation circuit 32 makes the alternator provide an alternator output voltage according to one of the control signal. When a pair of the command signals are generated alternately at a cycle shorter than a cycle decided by the response time of the alternator, the control voltage setting circuit 31 provides an alternating control signal so that the alternator 2 generates a middle voltage between the upper and lower desired voltages.
