    • A power feeding apparatus (14) for solar cells has: a voltage regulator (30), i.e., a voltage adj usting unit; a relay (34), i.e., a switch unit; and a control unit (36). The voltage regulator (30) executes voltage adjustment with respect to an input voltage, and outputs, to a power output terminal (20), a voltage adjusted to a previously set voltage or lower. The relay (34) is provided on a bypass line (32) that is connected between a power input terminal (18) and the power output terminal (20) without having the voltage regulator (30) therebetween, and the relay performs switching such that the bypass line (32) is connected or interrupted. In the cases where the input voltage is equal to or lower than the predetermined voltage, the control unit (36) performs control such that the bypass line (32) is connected by means of the relay (34), and the input voltage is outputted from the power output terminal (20).
    • 一种用于太阳能电池的供电装置(14)具有:电压调节器(30),即电压调节单元; 继电器(34),即开关单元; 和控制单元(36)。 电压调节器(30)相对于输入电压进行电压调整,向功率输出端子(20)输出调整为预先设定的电压以下的电压。 继电器(34)设置在连接在电力输入端子(18)和电力输出端子(20)之间的旁路管线(32)上,而不具有电压调节器(30),并且继电器进行切换,使得 旁路管路(32)连接或中断。 在输入电压等于或低于预定电压的情况下,控制单元(36)进行控制,使得旁路线路(32)通过继电器(34)连接,输出电压被输出 从电力输出端子(20)。
