    • An inventive series-regulator-type direct current power supply includes a power transformer of which a secondary winding has a plurality of output terminals, a plurality of corresponding rectifier systems connected to the output terminals, an input voltage-detecting circuit detecting a predetermined level of an input alternating current voltage, and a switching circuit opening and closing a line of the rectifying circuit systems. The inventive system selectively switches the output terminals of the secondary winding of the power supply transformer and switches the rectifying circuit, in response to a change in the amplitude of a primary input voltage in order to suppress a variation of a direct current output voltage.
    • 本发明的串联稳压器型直流电源包括一个电源变压器,其次级绕组具有多个输出端子,多个对应的整流器系统连接到输出端子,输入电压检测电路检测预定电平 输入交流电压,以及切换电路,其对整流电路系统的一行进行开闭。 本发明的系统响应于初级输入电压的振幅的变化而选择性地切换电源变压器的次级绕组的输出端并切换整流电路,以便抑制直流输出电压的变化。
