摘要： A generation indicating apparatus for a vehicle alternator in a generating and charging system includes an indicator lamp connected in series with an electric load and the series circuit of the indicator lamp and the electric load is connected to a battery through a key switch. A series circuit of an electric load drive transistor and an indicator lamp drive transistor is connected in parallel with the series circuit of the indicator lamp and electric load and a junction point between the indicator lamp and the electric load is connected through a line to a junction point between the two drive transistors. Either the load drive transistor or the lamp drive transistor is made conductive depending upon whether a voltage built up by the alternator has reached a predetermined level or not.The generation indicating apparatus includes an abnormal voltage detecting circuit and an oscillator circuit, and when an abnormal voltage is detected on the line between the junction points of the indicator lamp circuit and the drive transistor circuit, depending on whether the alternator is in a generating condition or not, either the electric load drive transistor or the indicator lamp drive transistor is controlled by a pulse signal from the oscillator circuit to become conductive only an on period of the pulse signal. A current flowing through either of the drive transistors is limited and the abnormal voltage level on the line is lowered at each of succession of pulse signals to ensure the restoration of the drive transistors to a normal operation after the abnormal voltage is removed.

摘要： A voltage regulator of a generator for vehicles includes an excitation control circuit for controlling the initial excitation of the generator and the full excitation succeeding to the initial excitation. The excitation control circuit also includes an indication lamp for indicating whether the generator is in a generating state or not. A generator output detecting circuit has a single input terminal to receive an output voltage developed in a stator winding of the generator and compares the output voltage respectively with a first reference level corresponding to an initial voltage build-up and a second reference level higher than the first reference level.An on-off control signal producing circuit produces an on-off control signal having a predetermined duty ratio and delivers the on-off control signal to the excitation control circuit until the output voltage of the generator reaches the first reference level, that is, during the initial excitation stage, thereby to excite the field winding intermittently with the predetermined duty ratio. When the output voltage of the generator reaches the second reference level, the indication lamp is extinguished to indicate that the generator is now in the generating state.

摘要： In a roadway vehicle having a storage battery and an engine-driven alternator, the battery voltage is controlled by a voltage regulator which has a first voltage detector for detecting when the battery voltage reduces below a higher reference level at which the battery voltage is normally controlled, and a second voltage detector for detecting when the battery voltage reduces below a lower reference level. A third voltage detector detects when the alternator voltage rises above a predetermined level. A logic gate circuit responds to outputs from the second and third voltage detectors by generating a warning signal. A semiconductor switching element is coupled in series with the field coil of the alternator to supply thereto the alternator voltage in response to a switching control which is generated in response to an output signal from the first voltage detector to cause the switching element to operate the alternator in a high output state and in response to the logic gate circuit to operate the alternator in a low output state.

摘要： In a battery charge indicating system, there are provided detecting means of an npn-transistor for detecting a closed condition of an ignition switch, and switching means of a pnp-transistor for supplying a base current to a driving transistor in response to an output of the detecting means, so that the driving transistor is made conductive when the ignition switch is closed and a generator is not generating its output. The emitter of the pnp-transistor is connected to a battery not through a current supply terminal for a voltage regulator, whereby even when the current supply terminal is accidentally disconnected from the regulator, the driving transistor is made conductive so that an indicating lamp is activated to indicate that the generator is not in the operation condition.

摘要： A voltage regulator for an a.c. generator produces a power generation ratio signal having a duty ratio corresponding to the current supply to the field winding of the a.c. generator. This power generation ratio signal is applied to an external apparatus through a signal wire. The duty ratio of the power generation ratio signal is more than 10% when the a.c. generator is normal. When abnormality is detected, the power generation ratio signal is partly masked by an abnormality detection signal so that the duty ratio of the power generation signal is reduced to be less than 10% and this change may be detected by the external apparatus. Alternatively, the power generation ratio signal may be transmitted only intermittently when the abnormality is detected.

摘要： A voltage control system for a vehicular power generator includes a receiver unit that receives voltage pulse signals indicating characteristics of the voltage control system from an external device with stability. The device periodically reads two cycles of leading edges or trailing edges, or two periods of high level pulses or low level pulses. When a difference between the two cycles or periods is within a predetermined range, the indicated value of the present voltage pulse signal is used to control the power generator. When the difference is out of the predetermined range, the indicated value of the stored previous pulse signal is used instead.

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.
