CHARGING SYSTEM

A charging system includes a multi-pulse transformer, n AC-DC conversion units, n power supply terminals and a charging scheduling apparatus. A plurality of secondary windings of the multi-pulse transformer form n winding pairs. The n AC-DC conversion units are coupled to the n winding pairs in a one-to-one correspondence. The n power supply terminals are coupled to the n AC-DC conversion units in a one-to-one correspondence. The charging scheduling apparatus are configured to detect the number 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. The M target winding pairs include 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.
