1. A charging system, comprising:
a multi-pulse transformer, comprising a primary winding, a magnetic core and a plurality of secondary windings, wherein the plurality of secondary windings form n winding pairs;
n alternating current-direct current conversion units are electrically connected to the n winding pairs in a one-to-one correspondence, wherein an input end of each alternating current-direct current conversion unit is electrically connected to a corresponding winding pair;
n power supply terminals are electrically connected to the n alternating current-direct current conversion units in a one-to-one correspondence, wherein each power supply terminal is electrically connected to an output end of a corresponding alternating current-direct current conversion unit; and
a charging scheduling apparatus, configured to detect the number M of charging devices and states of the power supply terminals, and determine M target winding pairs from the n winding pairs for supplying power to the charging devices;
wherein the M target winding pairs comprise a winding pair distributed close to a first end of the magnetic core and a winding pair distributed close to a second end of the magnetic core; wherein n is a positive integer greater than or equal to 3, and M is a positive integer greater than or equal 2.
