    • In a circuit arrangement for measuring a starting of rotation of a generator having an exciting winding and three-phase windings, a voltage regulator regulates an output voltage of the generator by influencing an exciting current, the three-phase windings are connected to one another at a point, one of the phase windings is connected to ground via a first resistor, another of the phase windings is connected to ground via a second resistor, a voltage across the first resistor is evaluated as a rotational-speed-dependent alternating voltage, this voltage is compared with a threshold voltage, and the starting of the rotation of the generator is detected when the measured voltage exceeds the threshold voltage.

    • 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.
    • 电池充电装置包括发电机,主电压调节器,辅助电压调节器,至少一个消耗装置和具有用于经由充电控制灯识别和发信号故障的电路部分的保护电路。 发电机输出电压用包含齐纳二极管的整流桥整流。 使用与阈值的电压比较和用于处理比较结果的逻辑电路来确定电池充电装置的操作中是否存在故障。 故障检测装置检测主电压调节器中的导通缺陷和/或发电机励磁电路的中断。 逻辑电路确定提供的电压是否同时超过阈值并且主电压调节器同时接通长于预定时间间隔以指示其连续操作。 在检测到故障之后,辅助电压调节器执行电压调节,直到故障消除,从而不会破坏整流桥。 所述的电池充电装置特别适用于机动车辆。
