Abstract:
A first multiple power sources control system, switching an originally used power source having an abnormal phenomenon to normal power sources to make loads keep obtaining supplied power and providing power calculation and load management to make a plurality of power sources in parallel connection to get larger power output, comprising:a plurality of power input sides used to receive a plurality of external independent power sources; a plurality of first voltage and current detecting modules used to detect whether said power sources of said power input sides is abnormal; a plurality of power output sides used to supply a plurality of loads with required power; a plurality of second voltage and current detecting modules used to detect whether power of said power output sides is abnormal; a plurality of power source switching modules used to switch a power source supplying said power output sides with power due to a signal of a control module; and said control module controlling a plurality of control switches to be in an ON or OFF state and controlling said power source switching modules according to a state informed from said first voltage and current detecting modules and said second voltage and current detecting module and can output a harmonic signal to said power input sides.
