Circuit and control method thereof

The application provides a circuit, comprising: a first circuit unit, a first end of the first circuit unit being used for connecting with an output end of a first inverter, a second end of the first circuit unit being used for connecting with a motor, the first circuit unit being configured to be in an off state under a first condition; the first circuit unit is used for absorbing energy impact, the second circuit unit is used for absorbing energy impact, a first end of the second circuit unit is connected with a first end of the first circuit unit, and a second end of the second circuit unit is connected with a second end of the first circuit unit. By arranging the second circuit unit, the counter electromotive force generated by the motor can be effectively absorbed, the failure of the first circuit unit caused by the impact of the counter electromotive force on the first circuit unit is prevented, the normal operation of the driving circuit is further protected, the motor is prevented from being stuck, an
