Claim 10:
11. The control system according to claim 10, wherein the sampling control circuit comprises:
a signal processing circuit; and
a control circuit; one end of the signal processing circuit is used as one end of the sampling control circuit to be separately connected to the first connection end of the alternating current power supply and the second connection end of the alternating current power supply, the other end of the signal processing circuit is connected to the control circuit, and the other end of the control circuit is used as an output of the sampling control circuit to be connected to a power supply drive circuit;
the signal processing circuit is configured to:
collect the voltages of the two ends of the alternating current power supply, and generate corresponding drive determining signals based on the voltages of the two ends of the alternating current power supply; and
the control circuit is configured to:
generate drive control signals based on the drive determining signals, and control, by using the drive control signals, the power supply drive circuit to turn on and/or turn off a corresponding bridge arm, wherein the power supply drive circuit comprises the first power supply drive circuit, the second power supply drive circuit, and/or the third power supply drive circuit.
