1. A power supply system comprising:
a first power output portion configured to output electric power supplied to an electric load;
a second power output portion different from the first power output portion and configured to output electric power supplied to the electric load;
a main pathway in a ring form and configured to provide a current pathway to enable flow of a current output from the first power output portion and a current output from the second power output portion;
a first output pathway connecting the main pathway with the first power output portion;
a second output pathway connecting the main pathway with the second power output portion;
a loading pathway connecting the main pathway with the electric load;
a plurality of main switches provided to the main pathway and configured to switch between a state, in which the main pathway is connected in the ring form, and a state, in which the main pathway is not connected in the ring form; and
a control unit configured to control switching of the main switches, wherein:
the control unit is configured to activate a non-ring connection mode that turns off one of the main switches and turns on a remainder of the main switches,
the main pathway includes
a first main pathway configured to connect the first output pathway with the second output pathway and
a second main pathway different from the first main pathway and configured to connect the first output pathway with the second output pathway, the loading pathway includes
a first loading pathway connected to the first main pathway and
a second loading pathway connected to the second main pathway, the main switch includes
a first proximity switch provided between the first output pathway and the first loading pathway in the first main pathway,
a first remote switch provided between the first loading pathway and the second output pathway in the first main pathway,
a second proximity switch provided between the second output pathway and the second loading pathway in the second main pathway, and
a second remote switch provided between the second loading pathway and the first output pathway in the second main pathway, and
in the non-ring connection mode, the control unit is configured to turn off one of the first remote switch and the second remote switch and turn on a remainder of the main switches.
