摘要： 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.

摘要： A power converter and a method of controlling the power converter are provided. The power converter includes a PFC rectifier module and a DC-DC converter module. When the output voltage of the power converter is greater than or equal to a minimum limit value of the bus voltage output by the PFC rectifier module, the DC-DC converter module is operated in a constant-on mode in which the DC-DC converter module does not perform voltage conversion and the PFC rectifier module outputs the bus voltage which is adjusted according to the output voltage of the power converter. When the output voltage of the power converter is less than the minimum limit value, the DC-DC converter module is operated in a voltage-regulation mode in which the DC-DC converter module converts the bus voltage into the output voltage of the power converter, and the bus voltage is a constant value.
