11. A current distribution circuit for plural power supplies, comprising:
a voltage amplifier;
a power converting unit having an input electrically connected to an output of said voltage amplifier and having an output electrically connected to a load;
a current detecting unit having an input electrically connected to said output of said power converting unit and said load;
a diode having an input electrically connected to an output of said current detecting unit and having an output electrically connected to said plural power supplies;
a regulable amplifier having a reverse input electrically connected to said output of said current detecting unit and said input of said diode, and having a non-reverse input electrically connected to said output of said diode and said plural power supplies;
an adding unit electrically connected to a non-reverse input of said voltage amplifier and an output of said regulable amplifier; and
a soft-start circuit electrically connected to said voltage amplifier and said regulable amplifier.
