Abstract

A DC noise absorbing device for preventing surges and regulating voltages includes a surge inhibitor, a fuse wire, a plurality of diodes, a plurality of Zener diodes, a plurality of diode alternate current switches (DIACs), a plurality of capacitors, and a circuit for indicating light emission, all of which are disposed on or between two wires respectively of positive voltage and negative voltage. The surge inhibitor and the fuse wire are connected in series on the wire of positive voltage; the plurality of diodes, the plurality of Zener diodes, the plurality of DIACs, the plurality of capacitors, which are identically specified, and the circuit for indicating light emission are orderly connected in parallel between the wires of positive voltage and negative voltage so as to form a staircase arrangement of cut-in switching voltages. The DC noise absorbing device provided by the present invention is connected in parallel with and between a DC supply and a DC load, for absorbing surges generated by switching the DC supply and the DC load, voltage fluctuations caused by load variation, serial surges rebounding from the DC load, and noises produced by external interference so that a stable operation and a promoted efficiency of the DC system can be achieved.
