    • A transformer employed in a power supply circuit of a ringing choke converter type comprises two feedback windings which share the current to be supplied to the base of a switching transistor for blocking oscillation. By virtue of the provision of the two feedback windings, a speedup capacitor for delivering a trigger current to the switching transistor is allowed to have less capacity, while the amount of heat generation of a resistor for regulating the trigger current can be restrained. These advantageous features of the present invention produces the effect that the bulk and weight of the capacitor and the resistor can be reduced, which leads to curtailing of the cost of the components as well as enhancing of the reliability of the circuit. The effect is more appreciable when a higher output is required.

    • A diode is disposed in the vicinity of a rechargeable battery. A current is applied to the diode from a current generating circuit. The current generating circuit comprises a thermistor which is responsive to the ambient temperature, so that a current associated with the ambient temperature is applied from the current generating circuit to the diode. The diode gives rise to a forward voltage drop, which is changeable as a function of the battery temperature. Accordingly, the forward voltage drop across the diode is changeable as a function of the ambient temperature and the battery temperature. The forward voltage drop across the diode is amplified to be used as a reference voltage. On the other hand, the rechargeable battery is supplied with a charging current from a power supply through a thyristor. The gate electrode of the thyristor is connected to receive the reference voltage and the cathode of the thyristor is connected to the battery. Accordingly, the thyristor is turned off if and when the difference between the reference voltage and the battery voltage becomes smaller than the switching voltage of the thyristor.
    • 二极管设置在可再充电电池的附近。 电流从电流发生电路施加到二极管。 电流产生电路包括响应于环境温度的热敏电阻,使得与环境温度相关联的电流从电流发生电路施加到二极管。 二极管产生正向电压降,其随电池温度而变化。 因此,二极管两端的正向压降可根据环境温度和电池温度而变化。 二极管两端的正向压降被放大,用作参考电压。 另一方面,可充电电池从电源通过晶闸管提供充电电流。 晶闸管的栅电极被连接以接收参考电压,并且晶闸管的阴极连接到电池。 因此,当参考电压和电池电压之间的差变得小于晶闸管的开关电压时,晶闸管被截止。
