摘要： A battery charger includes a transistor inverter. The transistor inverter includes an oscillation transformer and a switching transistor for controlling a current flowing through a primary coil of the oscillation transformer. This current charges the battery when the transistor is on. While the switching transistor is in an off state, charging current is supplied to the battery from a secondary coil of the oscillation transformer. The period of time where the switching transistor is in an on state is controlled depending on the amplitude of a supply voltage. Accordingly, the average value of a charging current to the rechargeable battery is automatically kept substantially constant despite variations in the amplitude of the alternating current voltage supply.

摘要： 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.

摘要： 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.
