Abstract

The invention discloses a control device of a traction converter. The control device comprises a voltage detection circuit and a transmission control unit, the voltage detection circuit is used for detecting the voltage of a power grid and outputting a voltage signal; and the transmission control unit is used for determining a power supply system of a line according to the voltage signal, calculating 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 system and the power grid voltage. The control device can automatically detect the power supply system and control the operation mode of the main circuit of the traction converter, the risk of manual misoperation is avoided, and the operation safety of the railway vehicle is improved. The invention further discloses a control method of the traction converter, and the control method also has the above technical effects.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a control device for a traction converter; and also to a control method for a traction converter. Background technique [0002] Due to differences in line power supply systems, rail vehicles need to alternate between AC (such as AC25kV / 50Hz, AC15kV / 16.7Hz, etc.) or DC (such as DC3000V, DC1500V, DC750V, etc.) power supply systems. For different power supply systems, the traction system of a rail vehicle needs a circuit working mode that matches the power supply system. If the working mode of the main circuit of the traction system does not match the power supply system, it will cause the circuit of the traction system to burn out and endanger the safety of the vehicle. The key to the safe and reliable operation of rail vehicles is to detect the power supply system of the line and carry out targeted control on rail vehicles. However, the current control scheme for...
