摘要： PROBLEM TO BE SOLVED: To provide a generator for internal combustion engine which can restrain noise of an generator. SOLUTION: At the time of driving a three-phase AC generator, relatively strong noise sometimes occurs under a prescribed condition, however, this device is capable of restraining noise occurrence by reducing exciting current IE under a prescribed condition. The reduction in the exciting current IE is conducted by a control mechanism 25. The control mechanism 25 can be constituted as the component member of a voltage controller 12. The conditions for the reduction in the exciting current IE are obtained from supplied or recorded information to output a driving signal A corresponding to this.

摘要： The battery charging apparatus includes a generator, main voltage regulator, an auxiliary voltage regulator, at least one consuming device and a protective circuit having circuit portions for recognizing and signalling faults via a charge control lamp. The generator output voltage is rectified with rectifier bridges containing Zener diodes. Voltage comparison to threshold values and logic circuitry for processing the comparison results are used to determine the presence of faults in the operation of the battery charging apparatus. The fault detection device detects conduction defects in the main voltage regulator and/or interruption in the generator excitation circuit. The logic circuitry determines whether simultaneously both a supplied voltage exceeds a threshold value and the main voltage regulator is turned on longer than a predetermined time interval to indicate its continuous operation. After a fault is detected voltage regulation is performed by the auxiliary voltage regulator until the fault is eliminated so that the rectifier bridges are not destroyed. The battery charging apparatus described is particularly suitable for use in motor vehicles.

摘要： A method and an apparatus for voltage regulation are proposed, by means of which the battery charge state and the loads from the on-board network are determined and suitable measures to improve this charge state are initiated if the battery charge state is poor. The on-board network load is determined during a first period (t1) from the switched-on duration of the switching transistor (18) of the voltage regulator (12) and the speed of the generator. In a second period (t2), the charge state of the battery is determined from the behaviour of the battery voltage at a reduced regulation voltage. … …

摘要： In the event of faults, a fail safe circuit FS is operative to energise a battery charge warning lamp LK and to switch connection of the generator field winding from a main regulator Re1 to a standby regulator Re2. A conductively defective main regulator state is detected when circuits 3 and 4 simultaneously give a high output to AND gate 5. Circuit 3 senses continuous field winding excitation by detecting a low average voltage on a terminal DF1, and the circuit 4 responds to the voltage at a terminal D+ being above a maximum value. Lamp LK is also energised and regulator Re2 brought into use if a circuit 6 senses interruption in field winding excitation. If the D+ terminal voltage drops below a first reference level, circuit 6 causes a load to be connected to that terminal for a preset period. If the D+ terminal voltage then drops below a second reference, lower than the first, then circuit 6 outputs a high signal to OR gate 2 to effect the change over to the standby regulator Re2. Gate 2 latches in the standby regulation state in response to a high output from gate 5 or from circuit 6. The fail safe circuit FS can be used with a generator having zener diodes Z in at least one of its rectifier bridges G1. When the ignition switch ZS is first switched on, a circuit 1 acts to switch the regulator changeover relay 8 back and forth once to effect cleaning of the relay contacts.

摘要： PCT No. PCT/DE94/00297 Sec. 371 Date Dec. 8, 1994 Sec. 102(e) Date Dec. 8, 1994 PCT Filed Mar. 18, 1994 PCT Pub. No. WO94/24755 PCT Pub. Date Oct. 27, 1994.The description concerns a voltage regulator (12) for regulating the output voltage (UB+) of an alternator (10) which is driven by an internal combustion engine. The voltage regulator (12) has an additional circuit (24) which evaluates the exciter current duty cycle (T) and supplies a signal (S1) at its output which is high when the exciter current duty cycle is high and low when the exciter current duty cycle is low. The circuit (24) is integrated in the voltage regulator (12) and the output signal (S1) supplied by it is transmitted via an additional regulator terminal (DA) and can be fed to the control device (25) of the internal combustion engine, where it is used, for instance, to increase the idling speed of the engine and accordingly also to increase the alternator speed and thus the power delivered by the alternator (10). It is also possible to switch off unnecessary consumers with this signal.
