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...
