Claims (1)
れか片方が負荷に直流電圧を供給する二つの直流
電源を有し、他方の直流電源が一方の直流電源よ
りも出力電圧が高くなつたときでも一方の直流電
源の出力電圧が所定の幅に入るように制御動作を
行う上限リミツターを備えたことを特徴とする二
重化運転方式用直流電源。 Each is connected to the load via a diode, and one of them has two DC power supplies that supply DC voltage to the load, so that even when the output voltage of the other DC power supply becomes higher than that of one DC power supply, one A DC power supply for a redundant operation system, characterized in that it is equipped with an upper limiter that performs a control operation so that the output voltage of the DC power supply falls within a predetermined range.
