摘要： A control apparatus of an AC generator for a vehicle can obtain large regeneration energy without making the size of the generator large. In the control apparatus in which an AC output current is rectified and supplied to a vehicle mounted battery (6) and an electric load of the vehicle, provision is made for a regulator (5) that controls a continuity rate of electric power supply to a field coil (3) of a generator (1) by controlling an output voltage of the generator (1). The regulator (5) suppresses the continuity rate of electric power supply to the field coil (3) at the time of steady operation of the vehicle, and switches a suppression value of the continuity rate of electric power supply so as to increase the continuity rate of electric power supply at the time of deceleration operation of the vehicle.

摘要： A starter protective device is provided which is capable of accurately determining the commencement of overrunning (i.e., timing of the commencement of starting of an engine) even in the presence of variations in the cycle of fluctuations in a battery voltage, noise and so on, thereby to prevent a starter from being overrun after starting of an engine in a reliable manner. The starter protective device includes an overrunning determination section 15 for determining when the starter motor 4 commences overrunning; and a starter motor cut-off section for interrupting the main contactor 3 when it is determined that the starter motor 4 commences overrunning. The overrunning determination section 15 detects a change over time of the battery voltage BV after the starter switch 2 has been turned on, and determines that the starter motor 4 commences overrunning when the battery voltage VB remains unchanged without any increase or decrease over a predetermined time T.

摘要： In a voltage control apparatus of an alternator mounted on a vehicle, the parameter and the equation, which are established based upon the power generation characteristic and the electromagnetic specification of the alternator, are not required, and both an ON-duty rate of an ON/OFF logic of a voltage applied to an energizing coil and a logic frequency can be established under stable condition within a preselected frequency range. The alternator voltage control apparatus is arranged by employing: a first logic output means for comparing a voltage generated by the alternator with a target voltage to obtain a magnitude logic which is outputted as a first ON/OFF logic; and a second logic output means for outputting as a second ON/OFF logic, a PWM internal output logic in which an ON-duty rate is increased/decreased based on the first ON/OFF logic by an increased/decreased amount defined by considering a time constant of the energizing coil. In this alternator voltage control apparatus, a logically processed result between the first ON/OFF logic and the second ON/OFF logic is used as an ON/OFF logic of a voltage application to the energizing coil.
