1. a multiple feed device, is characterized in that, comprising:

  • One power unit, has a power end and multiple sense terminal, and those sense terminals receive multiple power supply ready signal respectively, and this power unit exports multiple power control signal according to those power supply ready signals;

    Multiple power-supply unit, in order to export multiple operating voltage respectively, and those power-supply units export those power supply ready signals accordingly when exporting those operating voltages;

    AndMultiple switch element, couples this power unit, and couples those power-supply units respectively;

    Wherein when this power unit does not start and those power-supply units one of them export this operating voltage time, the switch element receiving this operating voltage exports a starting resistor to this power unit, this power unit is started and enters operating state, when this power unit does not start and those power-supply units of part export those operating voltages, one of them receiving this switch element of those operating voltages exports this starting resistor to this power unit;

    Wherein, when in running order and those power supply ready signals of this power unit one of them for activation time, the power control signal that this power unit activation is corresponding, those switch elements transmit corresponding operating voltage to this power unit according to the power control signal of activation, when this power unit is in running order and those power supply ready signals are partly activation, one of them of the power control signal corresponding to power supply ready signal of the above-mentioned activation of this power unit activation, those switch elements transmit corresponding operating voltage to this power unit according to the power control signal of activation.
