    摘要： Electric generator control for a motor vehicle in which the field current IF provided to the field coil of the generator is variable between two values in response to variations in the load applied to the battery. The output voltage of the battery is compared to a predetermined reference value, and a signal representing the difference is supplied to a voltage divider and to an integrator circuit. The outputs of the voltage divider and the integrator are then provided to respective, comparators. A reference signal provided by a time variable signal generator is supplied to both comparators, the respective outputs of which are connected to the inputs of an AND gate which controls a gating element which in turn controls the field current. In the case of a sudden increase in load applied to the battery, the output of the integrator responds more slowly than the voltage divider, which tracks the difference signal instantaneously, and the operation of the power switch is controlled by the output of the integrator circuit.

    摘要： An apparatus for monitoring the energy supplied by a source to a load system including sensors which provide signals proportional to current and voltage to a multiplier which produces a signal proportional to instantaneous power. The power signal is compared with a reference and the difference is integrated over a preselected interval of time at the end of which the integrator is reset. The integrated signal is compared with a second reference and the difference is applied to a comparator. If the resulting signal exceeds a set limit an alarm is actuated or selected portions of the load are disconnected from the source. A delay circuit prevents actuation at the beginning of the integration.
