The invention relates to a railway vehicle permanent magnet motor driver which comprises an energy storage device, a high-voltage input electromagnetic interference filter (EMI), a direct current filter reactor (FL), a direct current support capacitor (FC), a discharge resistor (Rc) and a DC/AC three-phase inverter composed of three-phase bridge type IGBTs Q1, Q2 and Q3. The energy storage device is output through a high-voltage input electromagnetic interference filter (EMI), two output ends are respectively connected with a direct-current support capacitor (FC), a discharge resistor (Rc) and a three-phase inverter in parallel through a main isolation contactor (KM1), and the three-phase inverter is connected with a three-phase motor; and the direct current filter reactor (FL) is connected with the main isolation contactor (KM1) and a circuit formed by connecting the direct current support capacitor (FC), the discharge resistor (Rc) and the three-phase inverter in parallel. The technical problem of motor driving of the intelligent rail electric bus is solved.
