Abstract
A control method includes, in response to detecting a target-type fault, determining, by a first control device managing a three-phase three-level power supply circuit, a control signal for instructing a first load to stop operating. The first load is connected to one of buses of the three-phase three-level power supply circuit, and the target-type fault is correlated with a second load connected to two of the buses of the three-phase three-level power supply circuit. The method further includes sending the control signal to a second control device via a target communication channel, to instruct the second control device to control the first load to stop operating.
