摘要： A power supply device includes a secondary battery and a charger, and can further utilize an external D.C. power supply. A switch is interposed between a negative electrode of the secondary battery and the ground. This switch is turned OFF when the external D.C. power supply is connected to the power supply device, and is turned ON when the external D.C. power supply is removed from the power supply device. The charger controls the charge of the secondary battery from the external D.C. power supply by regulating the potential of the negative electrode of the battery. A contact remains OFF while the external D.C. power supply is connected to the power supply device. In consequence, a current does not directly flow from the external D.C. power supply to the secondary battery. Therefore, a back-flow prevention diode, which otherwise results in power consumption, need not be disposed between the secondary battery and the load.
摘要翻译： 电源装置包括二次电池和充电器，并且可以进一步利用外部直流电源。 在二次电池的负极和地之间插入开关。 当外部直流电源连接到电源设备时，该开关关闭，并且当外部直流电源从电源设备中拔出时，该开关接通。 充电器通过调节电池负极的电位从外部直流电源控制二次电池的充电。 当外部直流电源连接到电源设备时，触点保持关闭。 因此，电流不直接从外部直流电源流向二次电池。 因此，不需要在二次电池和负载之间设置逆流防止二极管，否则导致功率消耗。

摘要： A booster type DC-DC conversion circuit and a voltage reduction type DC-DC conversion circuit are connected in series with a battery. When battery voltage is high, the booster type DC-DC conversion circuit does not operate, and the voltage reduction type DC-DC conversion circuit outputs a constant voltage lower than the battery voltage. When the battery voltage drops, the booster type DC-DC conversion circuit operates, and converts the battery voltage to a constant voltage higher than the operation voltage of the voltage reduction type DC-DC conversion circuit. The voltage reduction type DC-DC conversion circuit outputs a constant voltage. The power supply apparatus can continuously output a constant voltage from when the battery voltage is high until it becomes low, and can efficiently utilize the battery capacity.

摘要： A heating element, such as a switching transistor, a choke coil, or the like, contained in a power supply apparatus, is arranged in such a manner as to be thermally coupled to a diode inserted in series with a power supply line. The heating element heats up in operation, causing the diode temperature to rise and thereby reducing the diode forward voltage drop.
