This application provides a circuit, including: a first circuit unit, where a first end of the first circuit unit is configured to connect to an output end of a first inverter, a second end of the first circuit unit is configured to connect to a motor, and the first circuit unit is configured to be in a disconnected state under a first condition; and a second circuit unit, where the second circuit unit is configured to absorb an energy shock, a first end of the second circuit unit is connected to the first end of the first circuit unit, and a second end of the second circuit unit is connected to the second end of the first circuit unit. With the second circuit unit disposed, a counter electromotive force generated by the motor can be effectively absorbed, to prevent a failure of the first circuit unit caused by a shock of the counter electromotive force to the first circuit unit, thereby protecting normal running of a drive circuit, and preventing the motor from being stuck. This improves safety performance of a vehicle.
