    • A control apparatus for a switching device which suppresses surge voltages at the time of current shutoff of a switching device to protect from overcurrents although the switching device is not in an overcurrent state, including a current sensor, a comparator, a timer latch, a control circuit, and a transistor. The current sensor detects the current of a switching device and outputs a detected voltage. The comparator outputs a signal when the detected voltage is equal to or greater than a reference voltage. When the time duration of the output signal is equal to or greater than a setting time, the timer latch outputs a surge suppression detection signal, based on which the control circuit outputs to the transistor a driving signal to turn off the switching device. The reference voltage is smaller than a reference voltage used when detecting an overcurrent flowing in the switching device.

    • A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current. Since the current difference between the instant charge current and the target current is relied upon to switch the charge rate between the first and second charge rates, the switching can be made at an exact timing truly indicative of the condition of the battery, which enables a rapid charging, yet assuring to complete the charging successfully.
    • 恒流电池充电器包括用于向二次电池提供充电电流的电源,以及用于监视被提供给电池的充电电流的电流监视器。 包括用于根据监视的充电电流来改变充电电流的控制器。 控制器计算预定目标电流和瞬时充电电流之间的电流差,并且当电流差超出预定范围时产生以第一充电速率改变充电电流的需求,并且在第二充电电流下改变充电电流 当电流差在预定范围内时的充电率。 控制器以规则或变化的间隔重复地产生需求以改变充电电流。 第一充电速率被设置为高于第二充电速率,以便在接近目标电流之前进行快速充电。 由于瞬时充电电流和目标电流之间的电流差异依赖于在第一和第二充电速率之间切换充电速率,所以可以在真实地指示电池状态的确切时间进行切换,这使得能够 快速充电,但确保成功完成充电。
