摘要： A voltage regulator of an automotive generator has a MOS transistor, flywheel diode, voltage detection circuit, and booster circuit. When a battery terminal voltage is below a voltage adjustment setting, current is supplied by a current supply circuit separate from a charge pump circuit to raise a gate voltage of the MOS transistor until the source voltage of the MOS transistor becomes greater than the reverse bias voltage of the flywheel diode, and the charge pump circuit output is applied to the MOS transistor after this specified value is reached. The charge pump circuit has an even number of capacitor stages.

摘要： A vehicular power generator control apparatus includes a switching transistor, a voltage control circuit, a high rotation speed detecting circuit, a leakage detecting circuit and a maximum conduction rate restricting circuit. The leakage detecting circuit detects leakage current flowing to a P-terminal. When the leakage current is detected, a maximum conduction rate set by the maximum conduction rate restricting circuit is changed from a small value at low rotation speeds to a large value. Thereby, field current flowing in a field coil is increased, a large voltage is generated at stator coils and current flows to a rectifying circuit to thereby reduce the leakage current which flows to the P-terminal.

摘要： A permanent magnet made of ferrite magnet material used for a generator may be irreversibly demagnetized by a factor such as current supplied to a field coil, temperature of the permanent magnet and/or output current of an armature coil. When the field current exceeds a preset value, and also the output current exceeds a preset value, the field current is limited to prevent the irreversible demagnetization. Thus, the irreversible demagnetization of the permanent magnet can be prevented, while ensuring a sufficient amount of the output power. It is also effective that the field current or armature current is limited when the temperature of the permanent magnet is in a range of possible irreversible demagnetization.

摘要： The present invention relates to a device which supplies a field current to the field coil of an alternator for a vehicle in a gradually changing manner. In the device, a pulse voltage which has a pulse width corresponding to a phase difference between output signals of first and a second counters (15 and 16) is generated by a maximum duty ratio limiting circuit (19). When the alternator output voltage becomes higher than a reference voltage, the full-scale count time of the second counter is shortened relative to the full-scale count time of the first counter. On the other hand, when the output voltage becomes lower than the reference voltage, the same is elongated to thereby increase the phase difference. A switching transistor (12) is provided to control the field current supplied to the alternator field coil in response to the above pulse voltage.

摘要： A power generation controlling device for vehicle includes a communication controlling circuit, a power generation voltage and excitation current controlling circuit, and a communication frame processing circuit. The communication controlling circuit communicates with an ECU using a communication frame. The power generation voltage and excitation current controlling circuit controls power generation based on power generation control information in the received communication frame. The communication frame processing circuit decodes contents of power generation control information (i.e., signal switching data) included in the communication frame based on a signal switching bit in the same communication frame. Two types of contents or more that are switched based on the signal switching bit are assigned to the power generation control information in the communication frame.

摘要： An apparatus for controlling power generation of a generator has a voltage detector and a power controller. The voltage detector detects a voltage of electric power generated in the generator. When receiving a first power control signal, the power controller controls the generator to maintain the detected voltage at a first target value. When receiving a second power control signal, the power controller controls the generator such that the power controller suppresses the power generation of the generator based on a difference between a value of the detected voltage and a second target value lower than the first target value so as to maintain the detected voltage at a predetermined value lower than the first target value. Therefore, even when the power generation is suppressed, pulsation of the generated electric power can be appropriately restrained.

摘要： A vehicle power generation control apparatus has a power supply circuit, a rotation detecting circuit, an exciting current detecting circuit, a torque detecting/maximum exciting current determining circuit, and an exciting current control circuit. The rotation detecting circuit detects a rotation speed of a generator (or vehicle alternator) and the exciting current detecting circuit detects an exciting current flowing through an exciting winding of the generator. The torque detecting/maximum exciting current determining circuit calculates a power generation torque of the generator based on the output voltage, the exciting current, the rotation speed, and calculates an inertia torque of the generator based on a change rate of the rotation speed. The exciting current control circuit suppresses the exciting current flowing through the exciting winding so that a change rate of a total sum of the generation torque and the inertia torque does not exceed a predetermined value, for example, during the idling condition.
