The invention discloses an electric traction system of a double current system inter-city vehicle. The electric traction system comprises an inverter unit, an alternating-current power supply circuit and a direct-current power supply circuit, wherein the inverter unit is used for converting direct-current power to a variable-frequency variable-voltage power supply to be supplied to a traction motor so as to drive the motor to work; the alternating-current power supply circuit comprises an alternating-current pantograph, a transformer and a rectifier, the alternating-current power is subjected to the current collection through the alternating-current pantograph, after the voltage is decreased by the transformer, the alternating-current power is supplied to the rectifier, the alternating-current power is converted by the rectifier to the direct-current power, and the direct-current power is supplied to an intermediate direct-current circuit of the inverter unit; the direct-current power supply circuit comprises a direct-current pantograph, a direct-current high-voltage electric appliance cabinet and a circuit filter electric reactor, the direct-current power is subjected to the current collection through the direct-current pantograph, the direct-current power flows through the direct-current high-voltage electric appliance cabinet and the circuit filter electric reactor, and then the direct-current power is connected to the intermediate direct-current circuit of the inverter unit. The electric traction system has advantages of simplicity in structure, high universality, good passenger carrying capability, and the like.
