Claim 2:
3. The control system according to claim 2, wherein the sampling control circuit is further configured to:
when the voltage of the first connection end of the alternating current power supply changes from being less than the voltage of the second connection end of the alternating current power supply to being greater than or equal to the voltage of the second connection end of the alternating current power supply, and the charging time of the first power supply drive circuit is less than the first target duration, control the first lower bridge arm to be turned off; and
when the voltage of the first connection end of the alternating current power supply changes from being greater than or equal to the voltage of the second connection end of the alternating current power supply to being less than the voltage of the second connection end of the alternating current power supply,
control the first lower bridge arm to be turned on, so that the charging time of the first power supply drive circuit reaches the first target duration.
