Abstract: Combined with the background of the Ukrainian dual-current electric locomotive project, in order to improve the quality of the dual-current electric locomotive equipment, the magnetic residual phenomenon of the dual-current electric locomotive traction transformer was studied, and a zero-capacitance voltage control strategy was put forward. The signal that the voltage of the stabilizing capacitor above zero was used as the trigger of the switch device of the four-quadrant converter, and the demagnetization current was generated. Based on the parameters of the traction system of the Ukrainian double-current locomotive, a simulation model was established to obtain the demagnetization solution of the traction transformer of the double-flow electric locomotive.

Key words: double-current electric locomotive, traction transformer, residual magnetism, demagnetization, oscillating current
