  "textContent": "A control device and a control method for a traction converter. The control device comprises a voltage measurement circuit and a transmission control unit. The voltage measurement circuit is used for measuring a power grid voltage and outputting a voltage signal. The transmission control unit is used for determining a power supply mode of a line according to the voltage signal, obtaining, by means of calculation, the power grid voltage according to the voltage signal, and controlling an operation mode of a main circuit of the traction converter according to the power supply mode and the power grid voltage. The control device can automatically detect a power supply mode and control an operation mode of a main circuit of a traction converter, thereby avoiding the risk of human misoperation, and improving the running safety of a rail vehicle.",
