摘要： A battery discharge control circuit is provided with a timer for timing the decision of the state of a battery loaded into a battery discharger between a discharged state and a nondischarged state so that the state of the battery is decided a predetermined time after the battery has been loaded into the battery discharger. The control circuit prevents the battery discharger from discharging an undischarged battery due to noise generated by chattering contact between the battery and the battery discharger in loading the battery into the battery discharger or due to the variation of the detected value of the terminal voltage of the battery caused by the influence of the self-healing characteristic and temperature characteristic of the battery. The control circuit also prevents the battery discharger from again discharging a discharged battery.

摘要： A voltage setting value for charging a battery starts from a first constant voltage level less than a full battery voltage and after a period of time the battery voltage reaches that first level and the charging current begins to decrease. The charging current decrease is detected and the voltage value is increased to a next constant voltage level and the process is repeated until the constant voltage level is reached that equals the full battery voltage. Each time the voltage level is changed the corresponding percentage of the battery voltage is displayed to represent the charging amount.

摘要： An AC power supply supplied from an outlet 11 is rectified by a rectifying circuit 13 through an input filter 12. The rectified power is supplied to a primary winding N1 of a transformer 14. A controlling circuit 19 has a switching device Q1 that controls on/off at predetermined timing. An FB signal that represents a power state of a load circuit 15 is supplied to the controlling circuit 19 through a transistor Q2. A comparator 20 compares a rectified voltage V3 of a tertiary winding of the transformer with a reference voltage REF3 and outputs an error signal. With the error signal, the transistor Q2 is controlled. Thus, the voltage for the controlling circuit supplied from the tertiary winding can be prevented from lowering against abrupt load variation. In addition, the output voltage Vo can be prevented from largely varying.
