摘要： An apparatus for controlling an on-vehicle generator is provided. The apparatus comprises a switching element, current detecting unit, setting unit and driving unit. The switching unit turns on/off an exciting current to an exciting winding of the generator, the switching element being driven responsively to a driving signal having an adjustable duty ratio. The setting unit sets the duty ratio based on (i) a difference between an output voltage of the generator and a target voltage value and (ii) a condition in which an electric load is disconnected from the generator, wherein the duty ratio is allowed to lower than a minimum value of the duty ratio depending on a generated state of the generator. The minimum value allows the exciting current to flow at a lower limit detectable by the current detecting unit, The driving unit drives the switching element based on the driving signal.

摘要： A voltage regulator for an automotive alternator includes a switching transistor that controls an amount of field current supplied to a field coil of the alternator. The switching transistor is controlled in an ON-OFF fashion, and output voltage of the alternator is always monitored by a detector circuit that detects disconnection in a circuit for charging an on-board battery with the output voltage. It is determined that the disconnection occurred when a difference between the output voltage at a time when the switching transistor is turned off and the output voltage at a time when the switching transistor is turned on exceeds a predetermined value.

摘要： A voltage regulator controls an output of an automotive alternator by controlling an amount of excitation current supplied to a field winding of the alternator. The amount of the excitation current is sensed by a sensing resistor as a sensed voltage appearing across the sensing resistor. The sensed voltage is amplified by an amplifier to obtain a detected voltage, an amplifying factor of which is adjusted based on an reference voltage precisely corresponding to the amount of the excitation current, and thereby the detected voltage is equalized to the reference voltage. In this manner, the excitation current is precisely detected without mechanically adjusting a resistance of the sensing resistor by function-trimming or the like.

摘要： A charging control apparatus for a vehicle, which controls a power generation of an AC generator for charging a battery, comprises: a switching circuit connected in series to a field winding of the generator; a comparator for detecting a voltage of a battery and comparing the battery voltage with a sawtooth wave of a predetermined period; a memory device for storing a value regarding a duty factor of an output of the comparator at the same period as the predetermined period of the sawtooth; a control value increasing/decreasing circuit for increasing or decreasing a control value as an output, thereby making the stored value coincide with the control value; and an AND circuit to calculate AND of the control value and an output of the comparator. By controlling the switching circuit by an output of the AND circuit, when an electric load is applied the duty factor of a pulsed field current which is supplied to the field winding is gradually increased from the present value of the duty factor, thereby preventing a sudden increase of a load onto the engine.
