Abstract：Usually，the DC side of the traction rectifier requires a series LC resonant circuit to filter out thepulsating component of 2 times the grid frequency. When the resonant inductor on the DC side had a short-circuitfault，the pulsating component would be transferred to the motor side，the problems such as torque...
