摘要： A voltage regulator of a vehicle AC generator includes a rotor having a plurality of magnetic poles, a field coil for polarizing magnetic poles, an armature having an armature core with a plurality of phase windings for generating AC voltage under the influence of rotating magnetic field provided by the rotor and a full-wave rectifier for converting the AC voltage into DC voltage. The voltage regulator is comprised of a circuit for detecting phase voltage of one of the phase windings, and a comparator for comparing the phase voltage with a variable threshold level formed from the phase voltage and providing an output signal. Even if the phase voltage is biased by a DC bias voltage due to leak in the armature, the rotation of the rotor can be detected.

摘要： A voltage regulating system of an AC generator for charging a battery of a nominal voltage includes a rotor having magnetic poles, a field coil, an armature winding, a full-wave rectifier unit connected to the armature winding, a rotation detection unit, a voltage control unit for controlling current supplied to the field coil. The rotation detection unit includes a comparator connected to the armature winding, a first circuit for providing a first threshold voltage that is higher than negative side voltage of the battery and lower than a half of the nominal battery voltage and a second circuit for providing a second threshold voltage that is lower than the nominal voltage and higher than a half of the nominal voltage.

摘要： A vehicle alternator control device has a power transistor, a flywheel diode, a voltage control circuit, a primary power supply circuit, and a secondary power supply circuit. When the alternator starts rotation, the secondary power supply circuit drives the primary power supply circuit when the alternator speed reaches a frequency equivalent to a speed higher than an engine idling speed. When the engine stops and the speed of the alternator drops, the secondary power supply circuit stops the primary power supply circuit when the alternator speed reaches a frequency equivalent to a speed below the engine idling speed.

摘要： A vehicular AC generator comprises a resistor for ground one-phase output terminal in an armature coil, a switch for connecting and disconnecting at least one-phase output terminal out of the other phases of the armature coil to and from the ground, and a control unit for controlling the switch. The switch is controlled ON and OFF in accordance with a voltage generated across the resistor. According to this configuration, in the event of occurrence of leakage current in the armature coil, the occurrence of the leakage current is detected based on the voltage generated across the resistor and the switch is closed, whereby the leakage current is allowed to escape to ground and an actual signal from the resistor is detected easily.

摘要： In a power generator, a start of rotor rotation is detected by utilizing a small AC voltage in a stator winding generated by a remaining magnetic flux. A leak current which flows to the power generator from a battery is passed to a negative terminal of the battery through a resistor temporarily connected in series so that a small amplitude of the AC voltage will not be masked by DC drifting component arising from the leak current. Further, periodically connecting the resistor to the negative terminal upon an increase in the leak current reduces an amplitude of the AC voltage.

摘要： In an alternator, failure in a power supply line connected to an output terminal of a rectifier is detected. Upon detection of a failure in this power supply line, power generation is suppressed for a predetermined period that is longer than the time constant of a field winding of the alternator. Preferably, a high voltage pulse is detected to discriminate a first condition where a single high voltage pulse is generated when an electrical load connected to the power supply line is cut off and a second condition where a high voltage pulse is repeatedly and frequently generated when a failure occurs in the power supply line. Only when the second condition is discriminated, power generation suppression control of the alternator is conducted.

摘要： Shift means shifts a rotation speed range to a low rotation speed side based on an electricity amount related to rotation speed. In the rotation speed range, driving torque of a generator is suddenly changes as a result of an increase of duty ratio of a switch due to a shortage of generation capacity caused by a reduction of a rotation speed of a vehicle alternator. Preferably, the shift means shifts the rotation speed range to the low rotation speed side by changing the adjust voltage based on the electricity amount related to rotation speed while the rotation speed is reduced.
