Kind Code:
A
Abstract:
PURPOSE: To suppress ruch current or overcurrent at the time of short circuit of one load unit while preventing voltage drop of power supply for other load units in an electric machine comprising a plurality of load units.
CONSTITUTION: The power supply 101 comprises a voltage conversion unit 105 and a switching circuit 102. The switching circuit 102 comprises breakers 103a-103n with overcurrent trip function and overcurrent preventive circuits 104a-104n corresponding to the load units LUa, LUb-LUn in an electric apparatus.
